Higher compression.

Are you looking for lower compression for any reason? You said that you like the deck height on the AFR's so i wasn't sure where you were going after the 5.3 and 5.7 question.

well, at this point im not looking for a reason to run low compression.. ill be using nitrous however... i thought part of the concept of a thinker deck was to prevent a head from warping

if your using nitrous then you want high compression. i just bought some livernois ls6 heads for under 1k shipped. And that was assembled with springs up to a .580 lift. the look good. not installed yet.
