AFR 265 BBC Heads... In this Chevy 454 Engine Build, the bottom end is pretty much together and so its time to take a look at the top end of this engine...hence AFR heads.
Most people know the top end of a engine is where a lot of power is made and also the engines characteristics on how it preforms in any given application.... (THE WRESTLING MATCH) How to get enough cylinder head and intake for the hero HP numbers, and not kill all the rest of the engines performance characteristics.... Big Ports and High Peak flow numbers sell, but sometimes leave a customer dissatisfied with engine performance.... Having been a person that had a flow bench and ported heads at one time, I learned it wasn't all about peak flow numbers. The low and mid lift numbers and port velocity have a very important part in the engine's over all performance...
So on this engine build I did a lot of research on cylinder heads offered, and went with AFR heads 3610-1, 265cc port BBC heads, the smallest port they offer for the BBC... Lets look them over together and we can review the many good points that I see in these very well made cylinder heads... These heads may not be everyone's choice for there application, but for this build, they will suit this engine perfectly....😀

I've ran these heads NA and boosted, the V1 I had needed the vent area opened up and also the oil drain back...otherwise a great head and yes your basically getting fully ported for $1000 cheaper... We even ran them on a 498ci blow the tires off rolling 55mph with 3.55 gears... Also have used some of the larger Rec Port.... I've had good luck out of AFR on BBC...

AFR is a high quality product I've been using them since they were Brownfield heads. Still remember they are mass produced the runouts of the seats are not going to be as close as you would expect them to be.

I ordered a set of these heads in June I was suppose to get them in July I called the other day now I won't get them till October I seen these same heads out flow all the rectangular port heads on a video at Westech and that's what sold me on them it was a 80 horsepower gain over stock heads on a 468 I will be using them on my 427 can't wait till I get them.

Hi Richard... I'm like you... All the tests I've read or watched have very good things to say about these heads and even some of the comments posted on this channel of people that have used them have been positive.... Hope you get your heads soon!!!

Excellent choice in cylinder heads- this whole engine was well thought out and really hits home with me. Not sure what your business is for a living but you should be building engines like this for resale.

@Myersmetalworks 3 жыл бұрын

Thanks Philip... Always enjoy your comments... And it sounds like you have a pretty in-depth knowledge of engines yourself... I built some performance engines for people years ago... Also had a flow bench and Sioux valve grinder and seat set and did a lot of head porting and carburetor modifications for people.... That's why I'm so impressed with these heads... But I got out of it years ago, and have been doing R/D Design work for company's I've worked for... Out on my own again and kind of feeling out my new direction.... Thanks for all your input Philip its appreciated...👍

It’s a pleasure watching you. Much respect. I enjoy the talent and time to blueprint and do the things that I value as important in a build. I also am doing a build with that 265 head. Just not sure how big on the shortblock and I have one person in mind who I would want to do the shortblock for me.

Thanks for sharing I bought the AFR 325 and a Super Victor then had them checked and fully ported,He cut the intake into at the middle to port like he wanted,,I have a 505 ci engine I may have to much head ,I may order a block and make a 565 ci for these heads to work, he recommended a 1350 cfm carburetor, Self Racing, Kevin did a great job, He did these heads about a year ago I got to get going!

@@Myersmetalworks I have do business with them for years and sad to say covid caused Kevin and Glen to pass away, Great family,y car is fast with the current 496 and Pro comp heads and if I install the new heads they claim I'd pick up a 1/2 second, I run 567 @ 123 on my last pass and I'm getting a little old to be going much faster! I just let it idle and deck it on foot brake,ofcourse it has a pro brake but the 496 is a fresh build and I shift it @ 6600 rpms, I running a large Howard's Roller cam that will really perform if I'd turn it up ,it's got all aftermarket bottom end and I wouldn't be scared to buzz it up but heck foot braking what's the use!LOL

Thanks Mike.... Its appreciated.... The cam shaft is a Comp Cams Part # 11-771-8 Its a cam I picked out myself for the the conditions and intent of the car it was going into... Its always best to call Comp Cams with your combination and intent of use for their expert advice... I don't remember the cost at the time of purchase... You could go to Comp Cams Web page with the part # 11-771-8 to get current pricing...

@richardsmith-qy6vl 2 жыл бұрын

Fddo you think with the cam shaft I have its a howards 235x241@50 618 lift I can make 550 hp or do I need to go up in camshaft like 248 x 255 any help would be appreciated thanks Rick427

@Myersmetalworks 2 жыл бұрын

Hi richard... More duration usually will help give you a higher HP number... But its hard for me to say for sure what size camshaft the engine would need to hit those numbers you'd like to hit.... To me its about a good combination of parts working together that give good HP Numbers.... You have good heads... Sounds like a good intake and I like the cam you have chosen for it and if your compression is pretty healthy It sounds like it sould be pretty close to the numbers you would like.... 👍

AFR is the best hands down. Can you let me know the brand name or part number of your valve compressor tool. I like the way it looked to work so easily. The pneumatic compressor I use belongs to the shop so I want something extra for my home garage. Thanks.

@Myersmetalworks 3 жыл бұрын

Very happy with the choice of AFR. Don't know if you are familiar with "Nick's Garage" channel, but he dyno tested a 454 with those heads, if interested... I have had this compressor for 25-30 years and it was used when I got it, so I don't know if they still make it or not. But it's by K-D Manufacturing Co.- Part #308. Don't know if the company still makes this one anymore. Hope this helps.
