Re: A460 BBF Head Flow
In its current trim at 12.2:1 and 528" is making about 905 and 725ft/lb. The heads are a little on the large side for the current build. I had the heads CNC'd and it opend the chambers up a bit and lowered my compression for the intentions of upgrading later.
I intend to open it up to a 572" and put some compression to it, Should go up to about 1025-1050 with a single 4.
How big was your BBC? Sounds like a nice build.
