Which head gasket for 76gts and forged bottom? TSIA.
The engine is 8.3:1 stock-inch LS1, PTK kit with a 76GTS, Z06 heads.... what kind of head gasket do I need? Thanks.
-edit-
Also, where can I get a full gasket set with the seals for the front and rear covers?

The engine will likely see high boost on 110 and meth at the track. High boost for me is gonna be about 15#s I imagine. Maybe more if my fuzzies grow after awhile. It will see somewhere around 10-12 #s on the street with mostly 93 and methanol. There is a Sunoco station here with unleaded 110, hoping for good things. Is that GM gasket good for this application? Any idea where to find a set of the rest? Thanks.

If the motor is not ringed run MLS gaskets. If the motor is ringed, run Fel-Pro 9199-PT Graphite gaskets or SCE Copper gaskets. It's a hit or miss deal with the copper though. MLS gaskets on an untouched deck are damn near untouchable though.
