I want to install my new AFR 185's for Grudge match#2 against my bros 02 Z06.
I am in need of some advice. I have a 351W with Forged TRW's w/a 13cc cup. My came is advertised a .512 but the cam card reads gross [email protected] and .230 duration.
Should I be concerned with P/V clearance?
TIA

What pistons do you have? I installed a set of 69 windsor heads with 1.94 valves on a 69 351 with TRW 2446 pistons. The valves touched the pistons above the valve reliefs. The reliefs were deep enough but the valves were touching above them because of the larger diameter. I think the AFR heads have 2.02 valves. If so, I would definately check them to make sure. We were using a bigger cam, but it is better safe than sorry. If the pistons are flycut for bigger valves then I would say no problem. Hope this helps.
