Guaging interest in a Set of Absolute Speed Ported LS6 heads
These heads have about 3-5k on them.
Stock chambers size should make 10.5:1 compression.
I have over 2400 already in these heads
They are stage II max ported heads with Stock valves to keep the mid range power. They flow awesome to have the stock valves still. you can upgrade the valves and have a 3000 set of heads. If the valves were enlaged you woudl see the CFM rise about another 15-20 cfm on intake and Exhaust !
1300.00 with valves no springs
flows:
LIFT Intake Exhaust
200 150 131
300 214 174
400 255 194
450 267 205
500 286 207
550 294 213
600 304 214
Tested with:
28 inches of H20
3.90" Bore
Radiused Inlet
