Need advice on my lq4 & 243 combo?
Thinking of buying some ported 243 heads milled to 53cc with 2.05 valves for a stock bottomend lq4 with a 231/237 589/595 112lsa cam my question is are those heads to big? would the compression be to much? cam the right size I'm new to this ls stuff thanks for any help in advance.

Kind of off topic, but related, I'm trying to mate a LQ4 up with a T56 in my CTS-V. I've read on here that some LQ4's have longer cranks in them that are not compatible. I have the cast of crank, does anyone have a link or know off the top of their head which cranks will mate with a T56?
