how much can i have my 799's shaved without causing valve issues, I'm gonna be running a torquer v3 231/234 .643/.598 111 lsa, stock bottom end, i don't want to flycut the pistons, i think thats a little over my head, so how much do u think is to much?

 

ill also be running a stock size head gasket, the car is an 02 ss m6, full bolt ons, not a daily driver, more of a weekend and nice day driver

 

Bump it up

 

from what ive read you should put them on before milling and measure the ptv clearance. with your cam

 

Yeah after more reading I think that's what I'm gonna end up doing

 

The best way is to install heads and cam; measure ptv clearance and based on that result decide how much to mill if any.
