Hello everyone ,

I'm looking for some set of LS6 heads ported by TEA with nothing less than 60cc chambers , stage 2 is preferred or even a set of TEA TFS 215 with powdered metal valve guides .

Thanks

"It depends on head gasket thickness. Some production changes were made from year to year. For example, cars equipped with the 806 heads used composition head gaskets that compressed to approx. .040". While later cars used a .010" thicker MLS gasket. It only takes .005" to change 1cc with piston deck height or head gasket.
Hope this helps.

The heads I have are a Stage 2 ported 853 centerbolt head, ported by TEA. They have around 4,000 miles on them with a mild cam. These have a 64CC combustion chamber, that has been opened up for a 4" bore. I just had them disassembled, cleaned, and checked, and:
-Had BRAND NEW Viton valve seals installed
-Were Vacuum tested, all ports sealed to AT LEAST 20in"

They will come completely assembled with:
-Comp Dual Springs (Ti Retainers ETC.)
-2.02/1.60 SS Ferrea Valves

Flow Numbers:
Lift---Intake-----Exhaust
0.1---66.8--------57.5
0.2---138.6------110.7
0.3---200.4------168.7
0.4---248.5------213.2
0.5---283--------240.8
0.55--295--------248.7
0.6---300.4------254.7

Higher flow numbers wont come from stage 2 TEA port work then you want stage 3 if that is so.

Have a pair of Trickflow 215's coming off my LS1 soon with Harland sharp rockers on them (not sure if you need the rockers or not). About 5,000 miles on them, all street no track time, awesome heads. Are you interested?
