Finally some Ford videos. Other then Ben an Dave everything is Chevy,Chevy,Chevy,LS,LS ..... Even parts magazine have 10 pages of rotating assembly for Chevy 1/2 a page for Ford.

Great content. Really looking forward to your evaluation of the 185 head

Nice, thanks dude for all this info you give us! For free! I remember scrambling through old fast ford and 5.0 magazines back in the day to find the best parts, you know bang for your Buck type deal. Defiantly are considering these for my newly acquired 5.0.

Thanks for doing honest videos. It really helps.

I watch so much of your stuff and can't believe I missed this video! I bought a set of these IDENTICAL heads from Aeroflow in Australia for my old mans 408 windsor and was surprised how well they were cast. Very nice to see your flow bench numbers back up what their flow bench testing produced too. Look forward to seeing how they go, thank you so much for this test!

Will you be doing the follow up video? Really interested, thinking of buying a set. Thanks for your awesome videos Eric.

I really like these vids. Tons of relevant information.

Nice. Thanks for the video Eric. I'd be interested to hear in the future about seat material quality and your thoughts after porting.

Dam that is impressive. Thank you for your time Eric may have to get a set someday for my wife's car.

Wow, that really is a nice looking head! Man that makes me want to build a real budget SBF...

Not a ford guy but it’s an awesome video to watch and learn from as always. Thank you!

Nice to see at least one company is putting out good Chinese castings.

What I noticed on the intake is that every number is bigger than the previous one. Points to good port stability.

I enjoyed the video and would love to see you work a set of AFR 225's. I have a set of AFR 225's on a 337 SBF making a conversion from Solid roller to Hydraulic roller for the Street.

I got a set and the guides were tight and the seats were a bit off. Also, valve spacing is off and individual rockers didn’t work as well as I wanted so I went to shaft rockers. Hone the guides a bit and touch up the seats and they run well

Great smooth casting...very consistant looking chambers...

Great video as always. I always worry about the accuracy of deck thickness for head gasket retention on small block ford , so I'll stick with my old AFR Renegades.

Thank you for the information!!

Yeah I do think Ill be buying a set of those for my 347 . Very good numbers and have had my eye on them since they first come out

Where is the 185 video!? Love your videos, keep up the ford content!

Wondering how much better it would have flowed on a 4.155 bore. Nice video thanks .

Those would be great on a 408w street engine or for a high torque 1/2 ton pickup stroker.

Thanks for the review, i'm wondering if cartridge roll'n the runners would help. Or would it not make much difference.

That's a lot better that the other Chinese Ford head you flowed about 6 months ago!

Getting hard to keep track of them all these days, that's the X head from them not the maxx series for sbf right?... Think flotek Used that casting for the hammer heads with the 8mm guides too. Seen a Canadian shop selling them as PW performance world too. Be interesting to see what the 185s do.

What is the best Cleveland style aftermarket flowing head for a 1971 SBF Boss Service block build ???

I noticed on the video you said it wasn't the promaxx head so if some one was to want this head that's you reviewed how do I go about finding which one it is

Great video! Have u ever flowed the cnc (shocker) versions? Very curious about those

Do you know how much a 440 906 stock head flows with maybe mild porting? Trying to get the right cam. Any info would be greatly appreciated.

Hey Eric can advise any of the other companies that sale this summit is asking about $2300.00 that is not much of cheap to me for knockoff.

The one thing that makes me laugh about all these China heads at least for sbf's is dart sells this 205 tweaked "afr" clone in the shp line, and AFR sells the tweaked dart pro 1 clone as the enforcer heads.... Private equity groups buying up all the brands are going to destroy this industry.

So how much is the 205 head if you could tell us 🤔

Hey Eric. I see that the heads are marked 205 and the flow numbers are pretty much in line with the FloTek 205 hammer heads but on the paper from your flow bench it sais these are the 210cc ProMaxx Projext "X". Can you Clarify which these are? I know they start off as the same castings but am trying to figure out if either company does extra work to the heads during assembly to differentiate them from one another and to see if the ProMaxx heads may actually flow more than the Floteks as is advertised. Thanks.

Also, there is difference between your numbers and those published on their site....I am new to all this so I am wondering why? ....Measuring equipment?

Did you ever get around to flowing the 185 ? If so what were it's numbers. Please and thanks

Thanks for sharing

Have you ever worked on SBF Gurney Westlake heads?

I know where you got those heads. been waiting to see this video...

Are there any FE heads out there that are good? We had BBM, BT, Trick Flow, now it is like a desert.

So are these flotek “the hammer” heads? I have been wondering about these for a long time. Assuming that these are at least the same casting that’s pretty impressive for a $500 head.

Afr renegade castings are now Chinese. It appears edelbrock and buddy bar can't supply

Eric, could you please post the 8mm valve weights for AFR 205, SBF heads? Our 205cc AFR heads are the older 11/32" stems. Thanks

I realize it's an apples to oranges comparison, but for a Street 427 (actually a 428, 4.125bore/4.0stoke) application, would it be 'better' to start with these heads or the TFS HiPort heads ? The reason I ask is because about a year ago, you really seemed to like the TFS HiPort 240 CNC version.

Do you have part number to order it

So is it a promaxx head or no?

Are these the project x heads?

You say most of the power from port work comes an inch before the valve and an inch after the valve. I totally understand how you port a head an inch before the valve, however, the only thing I can think of an inch after the valve would be deshrouding the valve and softening the chamber. Is this what you mean or is there something else I’m missing?

What company in china got from

Anyone know which “brand” these are ? I’m looking for some budget heads for a 351 build that I eventually plan to stroke and these look like they would be great options.

Hello Tried looking for these on your website. Didn’t see them. Can you point me in the right direction to finding some? Ty

Do you have a link to buy these heads?

I made good hp with the 347 i built with victor jr. Ported head super victor intake 670 690 lift 264/272@.50 at 12.5 to 1 made 590 hp at 8500 rpm it sucked trying to drive at low speeds in the pits but was nasty up top i think i could have made more with the newer technology and stuff thats out now

Link to how to buy??

Would this company happen to offer a Twisted wedge 205

They say machined and assembled in the USA on their website

Where can i buy a set of these, really need to know. Thanks.

Where can I get a pair?

So where could I get a set of these?

Any link to buy them?

Where can I buy these heads from?

Flotek Hammer

So.......are you willing to port a pair?

Who can be buy that head from.

For all you Chevy SB guys a 220/2.180 ----227/ 2.34 port sq inches respectively VS the Ford 205 head at 2.30 sq.inches . So please stop comparing runner sizes !!!!!!! The AFR 220/227 and the Ford 205 work well on 400 chev ,,,408 ford for street/strip engines being well proven . 220approx 6500rpm the 227 7000 rpm and the 205 upto 7000rpm

Cartridge Rolling?

Commenting 😎

there no such thing as good Chinese anything

I used to be a ford guy.. now it's all about LS!

That's cuz I need all them Pages for Chevy parts to keep fixing that garbage when it keeps breaking down
