are you talking about the LQ9 heads? they are LS6 heads with bigger chambers for lower ion- in short. but they are for a 6.0
Youd have serious compression issues with them on a 5.3. Too low for boost on stock pistons if I had to guess. proboly the low 8s to high 7s?

Trey, no. The newer 5.3s have a higher flowing head.
Zippy is saying they are LS6 castings tho...
I had thought, maybe there was a reworked 5.3 head from gm.
Guess not.
Thanks.
