Guys, I have an LQ9 that I was planning on putting in a regular cab 1500 Z71. Anybody now what an LQ9 compression would go to with LS6 heads. I have a pair that was taken off the CTSV and wonder how high the compression would go. Or, would I be better off to mill the stock heads from the LQ9? thanks.

 

Compression should be ~ 10.8:1 I believe

 

should be the same as an ls2.
