Race winning brands is the private equity group that you are speaking of, they are screwing up all the entire HiPerformance market today. As far as CHI and CID and Higgins I was involved in their port designs and manifolds also. CID is in Minnesota and the castings come from Profiler, I hope that helps.

Thanks for the time taken, to inform us.

Good video.... my time was well spent.... alway's good to know what goes on... behind the scenes.... I remember when all there was.... was Brodix and Brownfields,... 1 on the west coast,... and 1 on the east,... good old days.........

Eric, good overview and insight. Thanks for the video

This was outstanding. thank you for your time.

I have been thinking to upgrade to head hunters for my sbf I havent heard too many folks running them im glad too see they are great

Thanks, have several friends running ProFiler stuff (BBC/ T/D type stuff) and love them. I'm getting ready to do a SBC/gen1 for my street MGB and like some of their options. Thanks again--great info

Ton of great info. Thanks for putting this together. I’m researching for BBF heads and it’s difficult because BBF seems to be all the big head guys’ side gig.

I really enjoyed your video, Eric.

Great great video. I've always wondered a lot of this

Great video Eric. Some really good information and opinions based on your experience. One head that I keep looking at for the Cleveland is the Scott Cook SCM heads. Another Australian head, but developed to look externally identical to the original Ford head, but in aluminium, and with a number of different port and combustion chamber options. Thanks again. Regards Greg

Great video, thanks for sharing 👍

That was great overview. you explained it well.

I ordered my Higgins sbf heads directly from them. Stand up people and excellent products. Zach Smith at ZSR engines in Missouri is now a dealer. He only does Ford engines though. He’s also a good dude. Ordered a lot of parts from him and when the time comes he at least do the machining and possibly the assembly.

25 years ago Trick Flow's heads and intakes used to flow like crap. Good to hear they've improved.

I would absolutely love to see a similar hierarchy tree focused on BB and SB Mopar, BB Ford, Other GM and maybe even AMC. Granted those crowds are smaller, but they love this stuff just as much.

Thanks for the information!

I used to work on a lot of those Pro Topline cast iron SBC and SBF for circle track guys. I believe that they became RHS. Thanks for another informative video.

Great information , many thanks.

Very fortunate to live above 1 Hr away from Higgins heads in Melbourne, Australia. We have a set of his LS3 heads, they’re brilliant and cost effective.

Awesome video !!! I wish you could do one for aftermarket Pontiac heads. There is a lot of misinformation in that area.

I would love to see a video of the best niche group of heads for each as well, like Chevy stuff has the Sonny’s, edelbrock big victor 3, etc. love the video tho man thanks a bunch!

Back in the day before for sbc iron heads it was the pro Topline heads😎 neighbor had a stock block iron headed sbc (408) made 650hp na. Also had a 200 shot single stage. Ran 9.80 na and 8.90 with the spray in a foxbody notch. Those old school pro Topline heads were sweet. Can’t find them anywhere now. It’d be like finding gold. Pretty sure when this motor was running in the mid 00’s those heads were already out of production and bought out 10 years earlier. Now it’s the known RHS pro action stuff but I’m not 100% sure if the heads are as good as they were when the New Zealand company was making them back in the 90’s, and I don’t think they even make an iron head anymore. Maybe I’m wrong.

Thanks for the info.

Great information thanks for sharing

The one thing i was always impressed with was Afr exhaust port flow. They werent huge cc but for sbf exhaust port flow is so good even compared to other aftermarket pieces. One company you didnt list is Performance world. It looks like a Canadian company that domestically machines foreign castings. They have HUGE cathedral ls heads that use offset ls3 rockers and have a 252cc intake port. They also have regular gen1 castings and huge rec port ls3 castings as well. I dont expect a set of these to cross your bench.

There are now so many aftermarket heads on the market now which creates a lot of study . Like a lot of things if your not dealing with these things often its hard to appreciate the differences . What you did was well layed out and cuts to the chase about your opinion on all these heads

Excellent video Sir! Much of what you said I have heard from others in the industry... I think your assessment was really good and honest with all the brands and You're 110% correct about firms and the threat of them buying out some of these "stand alone" companies. It sucks but like you said, someone throws a bunch of money at you-what are you gonna do? My hope (like everyone else's)is that AFR, Brodix & Profiler stay strong and keep "doing them" so to say. I am surprised though that TF especially since they are owned by Summit don't have their own foundry. That I was not aware of 🤔

Currently using Flotek on a sbf - seem to work good, but there was work needed on the intake ports to get them to match the intake. It appears that there is some core shift. I have heard about this from more than one user.

Excellent video Eric I just wish your audio was a little better I have a hard time hearing you because I have a hearing disorder

Great information.

My engine builder recommended Liberty for my build. He said their head was a good bang for the buck. It's the first aluminum headed sbc engine I've had. So far so good. No fancy script out front but I'd. The engine runs good and has not had any issues so far.

Great video Eric I mostly do LS builds , mostly FI my go to for big inch is all pro for smaller i find PRC is hard to beat… any thoughts?

Eric , what do you think about CFE? As far as TFS, has the hardness of the head improved? Kaase made a really good flowing SBF head 10 yrs ago which were Canted with good flow numbers. Unfortunately, they're no longer in production

What are the heads you are using on this engine and the intake. Sure enjoy your videos just subscribed and liked👍🤙🏻😁👌

Great video! This is the information I've looked for for 5 years. 3 of those years were wasted simply trying to get hold of ProFiler sbc heads! Refuse to answer emails! Won't answer phone calls! And in the end I'm convinced all ProFiler wanted to do was give potential customers the worst customer experience possible! And that's people just trying to buy there cylinder heads! Dealing with that company was like getting your teeth pulled out your head without anaesthetics

Hey Eric! First of all, love the videos, I have learned a lot from them. Question, I have a sbc (327) and I'd like to beef it up a bit. It's a street application so I'm looking for power gains throughout the power range. From what I have read/researched, folks are upgrading to the AFR 195 heads with an applicable cam (comp XE274). In this video you mentioned that Profiler makes the best sbc head in your opinion; is that for street or race applications? Or both? Thanks in advance! Would you stay with the AFR/comp combo, or maybe the Profiler/comp combo?

you need to look into Higgins Race Heads. also MBE and AllPro are my pick from USA from downunder.

CID has a symmetrical port BBC head that I saw make 100 more hp when bolted on a motor even when they had to use a smaller cam because of valve angle .

Good Video … But can we please have a similar video for the Mopar 383/400/440 and can you please do a full review of the Trick Flow 240 & 270 head for the 440. Thanks.

Hi, do you have any info or an an opinion on the ford Z304 heads, I have a set of the 1st line up sitting in the boxes for about 10 years, " one of those deals that I thought I couldn't pass up even though I didn't need lol" was wondering if they are worth getting ready for the track, drag, thanks for your time

Cash , quality and performance combined....AFR is tough to challenge..oh and dont forget about the edelbrock victor/glidden head...that dam thing is Krazy good!!! if you have Deep Pockets!!

Oh wow I never heard of the 3 Australian brands also the 3 brands you mention Dart, World Products, and EQ they are circle track heads for sure I know quite a few people use 1 of those 3 and I use World Products for my wingless sprint car I am getting into. They are 220 runners and 208 intake and 160 exhaust I don't know the flow numbers but I tried to look them up I guess they flow 290cfm peak but I don't know I never found good proof of them.

Thank you Eric.

Ty for this, Brodix it is.

Are the valves that come on the liberty ls1 heads any good or would they need to be purchased bare and fitted with other valves? Would these heads be better as cast than a set of 243/799?

I believe the Flowtek heads are manufactured in Evansville, Indiana

Just subscribed and have been looking through your library but can't seem to find anything on the AFR V2 Heads. Purchased a set of 335 for a twin turbo race motor. I was told the AFR had .250 more meat on the deck so works best on turbo applications. AFR were super supportive even going as far as swapping out springs due to the lighter rates on the as sold Heads. AFR are really great to work with IMO. Originally had a set of Dart Pro One of the same size that needed work. Tried to get them refreshed at Dart (World Mach.) And couldn't even get them to answer. I would appreciate any ideas you may have. Mark Samford in Abilene massaged em lightly. (Guides/chambers)

Hey Eric, are you a fan of the Brodix BR7 LS Heads ? or would you point someone to the higher end Dart LS heads instead ?

Your not the only ones paying through the teeth for Higgins heads , there a high quality expensive top end head, down here in Australia you rarely see then in the wild , for the most part there on top end builds where the cost of the parts isn't there biggest concern 😟

I just bought a set of afr head 1451 work great 9.40 best time.

In my experience which is limited. I have found for bang for your buck and being ready to slap on and go I find afr being superior. I love my brodix heads but they took some work to get where I am today

I'm thinking of getting another Ford soon for me it's easy, either AFR or TFS only. Both proven performance, quality from sound companies.

That's funny, I compare Dart & Brodix as well. Brodix just reminds me of old racer stuff your dad would use. Dart and AFR has newer age appeal.

Great video thanks. Any intel on AllPro or Australian casting Racer Pro?

Good review! I need to do the heads on my C6Z/LS7, I'm strongly considering the PRC 285 Texas Speed heads. Thoughts? They seem like one of the better values with decent flow numbers.

All of Higgins current port and manifold design is done by GP Technologies (Gale Powley) Higgins is adding more heads LS, Ford and now SB chevy

Great content Thank You which Trick Flow twisted wedge heads would You recommend for a good street able 347 SBF with an Edelbrock Pro Flow 4 system backed up by an AOD and 3.73 gears in a 92 Fox Body coup . Any information that You can share will be greatly appreciated , Thank You . 🇺🇲🇵🇷🦊👍

What cam is in the truck sounds nice.

Love dart cast iron heads

Seen a 13 degree ALL PRO headed 468ci SBC produce over 950hp NA.

Is it wrong that I’m a AFR fanboy. I’ve always had great luck with them and everyone I know who has ram them has great luck.

Edelbrock makes ford racing intakes too!

I heard when edelbrock purchased the comp performance group or whatever they shut down rhs because edelbrock didn't want a second cylinder head division

I have a set of victor jr sbc heads are these performance oriented are like stock replacements should I get rid of them and switch to something els I think there from the early 2000s there on a 383

do the blueprint heads feature a .500 raised exhaust port? if so do you need special headers to run them?

one aussie one you missed is torque power... yea they only do holden atm but they do it good.

What is your take on trick flow twisted wedge clevor heads

going about private equity. at current trend to energy cost, they are unlikely to snap a company with foundry, unless more "affordable" tracks built and events.

You ever come across Skip White Performance NKB heads? Made in China but supposedly use a high grade of aluminum. PBM valves, Comp springs, retainers and locators.

I was surprised AllPro didn’t make the list.

What do you think about the Brodix Race Rite sbc heads?

Hi Eric the PRC's are Supposed to be Cast here in America by Texas Speed, I've bought a pair for my LS1, then decided that even though the bore was good I put the LS1 on the shelf and got me a 427 Stroker using my 6.125 rods and the PRC Heads ,hope they don't hold me back to much I'll use them and the Johnson Link Bar Lifters 1.7.1 Roller Rockers, until I can get up some more cash for some cnc billet Ported LS7 Heads and will need to change intakes ,and to do it right ✅️ that's another 6 or 7 grand ouch ,,,,so Eric 427 Stroker 235 246 ,635 lift with the PRC'S, they are milled down to 60 cc pockets, cause incase going to run them on the LS1, I kinda blew it ,or else Texas Speed would have took them back if I didn't have them mill them down ,,,, I hope they run Strong on my 427 Stroker it's a street car 914 Porsche

What about CFE and Allpro? Is this vid just sticking to OEM valve angle stuff?

Been thinking about buying AFR 180cc eliminator for my sbc350

I didn't see Randy Brizinski on the list He puts out some pretty good flow numbers.

What do you think of the afr 335 bbc enforcer heads ?

Were the trick flow sbf twisted wedge heads any good? I always wanted a set of them back in the day.

Edelbrock heads are still cast and finished in the USA. I just bought and installed a set of the e-street (budget line) heads. Received last week and installed this week (27 May, 2022) from Summit.

How much lift on a cam is needed, to get the best use out of Brodix head hunter SBF? For street use,

I was looking at putting a set of the afr 227cc eliminator race ready racing heads on my sbc 406. Looking to put a big solid roller cam in the engine to go with the heads. Looking to have my compression ratio at the 11:1 or so and looking to make 500 to 600hp. This is just gonna be a play toy for the street and maybe track time. But still want to be able to drive it to work and daily drive still. Would the heads be a good choice for me?

What about ALL PRO ? Not included ?

Thanks

How do the gm heads conpare?.. like the fast burn small block head?...

Which head would u recommend with a sbc with a single turbo? I have a 3.25 stroke and run flat tops also running an e85 blow through setup I was told that I’d really See a change with the afr 195

chapman did a lot of mopar stuff and they started out with mopar giving them garbage to work with but later design was amazing

I know this is an older video and I apologize but what was your thoughts on MBE for small block Ford. I'm pretty much talking about small block Ford for everything... Original OG Fox body guy... Grew up with them

Seems nobody here mentioned Frankenstein engine dynamics products, they make their own heads and manifolds, I run their m311 head with their low ram sniper, what I like is the heads and manifold is designed for each other port matched and flow tuned .

In your experience, what is the best flowing factory BBC head ? Have you had any experience with the new Speedmaster line yet ?

Did you test all these heads or is this just your opinion?

Interested in knowing your opinion on who makes the best sbc 23 degree head. From a perspective of out the box to potential to for room to grow for all out hp. (My non professional opinion is afr)

Just settled for airoflow alloys due to not really been able to get any others these days ,, love to know if anyone has used them on BBC?

Should I be concerned about the rocker studs protruding down into the intake runners on my new afr sbc 195’s

Let me ask you a question years ago I bought a 1967 nova ss with a super high reving small block like 10,000. Rpm high on the build sheet the heads were listed as brownfield heads the castings were brodex was brownfield a porting guru or have you ever heard of him or that company

Have been impressed with my AFRs. Well made, make great power.

Hey Eric, could you do a cylinder head a Edelbrock 12° big block, head specs and flow numbers

just call higgins in australia and becoem a dealer. i cant see it hurting there company

I've heard that brodix has the best small block mopar head as well.

What is the best heads for 5.3 L83 with btr stage 2 cam Looking to get the best Preformance Thus us a daily driver If you have what you what I need I’m interested in purchasing

I would say stock for stock unported in my opinion if you just want to bolt on a head and go drag racing with a sbf its afr. Followed closely by trickflow 11r. Now ported that changes a bit but im running old school svo y303 heads that have been opened up so much they are almost unrecognizable from the stock version 😂
