243 LS heads - fully assembled

Are you sure. Surely a larger cumbustion chamber wouldn't drop compression..... Bump for a good seller and thread crappers

Not if they're all the same casting number. 799/243's are the same no matter what engine they come off of. 5.3, 5.7, 6.0 have all used 243/799 heads at some point, and they're all the same.

Thanks guys...
