Do u need to up grade valve springs or retainers to run high compression pistons??
say u have gsr block and you run ctr pistons which upst he ratio to like 12.5, do u need to upgrade the reainers or valve springs. Oryou can run it just with the pistons?
Well what if you plan on just revving higher than the rev limiter. Or in my case if I have a chipped ecu w/o a limiter and dont wanna drop a valve from a mis-shift--especially when I finally get my snail on.
