Default Ls1 to lq4

So this what I have:
Ls1 currently in my 1998 z28 camaro with a t56.
Lq4 from a 2005 2500 hd
I have a few question about what would be better as far as heads.. Should I keep the lq4 heads or swap the ls1 heads onto the lq4. Lq4 heads are I think 67cc with a 210cc intake runner and I think the ls1 heads are 61cc with a 205cc intake runner. Please correct me if I am wrong. Just wanting some thoughts. And will post more as I progress in this build. Also my intentions with the ls1 is swap into my 1986 c10 later down the road. So ideally would be keep the 10:1 cr with the ls1 heads rather than lower the cr by using lq4 heads on the ls1. Also can pick up a set of heads from a lm7 pretty cheap. I have several ways to go just hope some one can help point me in the right direction. Another route would be mill the lq4 heads. Looking for 10:1 to 10.5:1. Will be running pump gas. Will be daily driven. And would prefer NA for right now. Any opinion will be greatly appreciated!

I would sell the stock heads and pick up a set of 243s from the classifieds here.
