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 Sun 2 Dec - 17:11

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
