Will I need to flycut pistons? I recently purchased some S2+ GTP heads that were milled to create 11.4 comp with2.02-1.57valves. I also bought the cam that was designed for these heads which is a custom 223-.581-112 (278? adv. dur). It's the fast ramp rate and the milled heads that concern me.
My question is would I have to flycut the pistons for this setup? Would I have to remove the pistons to do it or disasemble the heads?
I planned on checking gap with putty/clay but I wanted to get some input before we get started so I know what I am in for.
I'll talk to Nick, G, and see if he had to do it when they were in his car but even if he didn't what are the chances of it not clearing in mine?

Re: Will I need to flycut pistons? To get 11.4 compression on a 5.7L head means a lot was done to the setup.. I would clay it first. If you have the ability to get it fly cut I would.. Thats just my opinion..

Re: Will I need to flycut pistons? Nick said they were designed to resemble the 5.3L heads. They were the ones on Nick Gette's grey WS6.
