i promise its the last one!

ok, so Ls1's have flat top pistons, correct?? and the "stock" c/r on a 98 ls1 is 10.19.... MY QUESTION IS, what would the c/r be if a set of -4cc dished pistons were installed??? can you correct that with milling the heads??


thank you.... and yes maybe i shoulda just had my engine built somewhere so i dont have soooo many friggin questions!
