Good question on the pistons. Based on that the valves are moved I'd think will need the intake notch relocated. The angle changes they listed don't make sense to me. They say the intake is 14° and the exhaust is 4° ??? Stock is Int. 9.5°x5°, Exh. 15°x4° and the Kaase SCJ/P51 Int. 8°x4.5°, Exh. 4°x4° so not sure what those angles they list mean.

Unless they are trying to incoperate chevy design into the heads.... IE 15 degree BBC heads.

Can't believe there isn't more discussion/excitement about this. In our small BBF world this is huge news.

Im sure someone on here had eyes on at PRI and has talked to the guys in the booth.

Let the technical discussion roll.

AFR bbf head

Post  Alvin on December 2nd 2012, 6:11 pm

I took a look at the AFR head at the PRI show. I "fingered" the ports and took some cell phone pictures. The head was a plastic prototype because they had not cast one in aluminum yet. The intake runners appeared smallish, about 270cc. The exhaust port looks a bit undersized also. I couldn't tell if it was raised, but the floor was filled and they had about as generous of a radius as could be expected on the short turn of a BBF exhaust port. They told me that the head should be to the market by May. I'll post some pictures unless someone beats me to it.

If you can post up some more pics that would be great Alvin. Any more info is welcome too. Even the junk ProCrap stuff fills a niche for this engine, and I'm hoping this is something more substantial. Cool

They talk about a new A460 head and give us another stock style low port head.

The stock intake valve angles you mention are not right.
They are not the same as a Cleveland.

X2.... I'm not gonna waste a bunch of time looking it up but, I was thinking the stock 460 stuff was 15*ish.

It'd been cool if the 429-460 had the cleveland cyl head package. Exclamation

Want to hear something funny Randy I took those numbers from YOUR post in this thread:

http://www.460ford.com/forum/showthread.php?t=105559

Scott Johnson in that same thread and on his website list the std Intake as "5 degrees / 9 degrees 30 minutes ( inclined in 2 planes) for the intake".

So guess once again I should know better to quick google something for an answer, at least my printed reference materials are correct... I'll just have to look it up the old fashioned way... As for cleveland valve angles I hope they did.

OK looks like stock 429/460 Intake is 15 x 5 . Cleveland Intake 9.3 x 4.15. Lesson learned always look in the book... the angles in the article now make sense too...

All that information was gathered from that year FRPP catalog which was later determined to be wrong.

Yes Randy, I see the wrong part. Seems once misinformation gets out, it is always out there.

You may want to go back and correct your old post for accuracy sake. Regards, Steve

Wow, I sure hope the springs in the 185's that are on my 5.0l are ok. It's been about 13 years since I put them on and I have never so much as checked the valves in that time.

AFR plans to do dyno tests against several heads, including the P51's.

They sure didn't talk those heads up at SEMA. Whomever we talked to didn't think they would be world beaters by any means. We were hoping to see another race head option.
