ok stock LS1 with stock ls1 heads is 10.5:1 compression.
when i switch to 243 heads what do i get?
and how much of the 243 heads do i have to mill to get 11.1:1 ( or real close) and if i mill that much will i have valve to piston problems?
thanks

the stock ls1 with ls1 heads is 10.1:1 with 243s it will bump up to 10.5:1. This thread has a lot of good info in it.
