I'm in the middle of the winter tear down of my race motor in my 68. Its a 406, with 195cc AFR heads. The car runs 11.05 all day without nitrous. Now part of the upgrade is a to step up to a solid roller putting the lift up to .645/.625 from .537/557. also a piston change to go form 11:1 to 13:1
Now my buddy has suggested for cheap i could buy his Pro Action 220 cc heads. they have a 4cc smaller chamber than my AFRs.
Does anyone have any experience with these heads? I know my AFRs work very well but I think the small port is going to be a limiting factor pretty soon.
