Really? What does that change over stock LS1 heads? Is it just a lil more compression?
I saw a set that were cnc'd w/ 2.02/1.60 valves, dual springs and tit. ret.. But advertised as LS6 heads.

Slightly smaller 62-63cc chamber, smaller cc runners.
2.02 is a slightly oversize (but common) intake valve size, but a 1.60 exhaust valve is huge.
1.55/1.57 is the norm on modded 5.3s.
LS6 heads are all numbered 243.
