Do I Need to Flycut With These Heads? Hey all,
I am looking at a set of CNC LS6 heads from CBM Motorsports. They use Manley one piece stainless 2.055 intake and 1.60 exhaust valves along with Manley polished Nextek dual springs # 221435-16 rated to .660 lift. They have 64cc chambers. I am currently running a TSP 228r cam in my LS1 with stock heads. If I purchase these heads will I have to do any fly cutting on my stock pistons; or should I be able to just bolt on and go with no problems? I didn't think that I should need to flycut, but I have heard that I may have to with these heads. I'd prefer not to buy if I am going to have to do some flycutting. I'm new to the head game, so bear with me if these are easy questions.
Thanks,
Johnathan

64cc is pretty much stock cc on a 243 head, they are 64-65cc stock
So I think you should be fine, however now might be a good time to measure piston to valve clearance so you'll know %100 and teach yourself a new trick..
