Rate my LS6 Stage-II Heads... Stage-II ported LS6 (243) Heads (local shop)
2.02" Intake valves
1.57" Exhaust valves
Superflow SF-1020
28", 3.90 bore
Lift - Int - Exh
-----------------
.200 - 141 - 114
.300 - 196 - 160
.400 - 252 - 190
.500 - 292 - 206
.600 - 319 - 215
Heads will be used to complement a Comp XE-R 224/224 .581" .581" 114LSA + 2 deg advance.
Lookin' for a little feedback on whether or not I should try and get them reworked for a bit better flow in the midlift, or if you think they'll provide some pretty darn good power as-is....
TIA!

They look great except for .300 value. Otherwise, very healthy.
Your cam won't take advantage of the good upper lift numbers however. Get something with a tad more lift maybe, to wring it out. Also, those heads beg for a little more duration; 228-230 won't kill ya.
