definitely get the steel LIM gasket, felpro sells both plastic and steel but i'd avoid plastic again... along with dexcool - just doesn't do too well when you get air in the coolant passages
i forget which, i think the instructions with felpro head bolts (or maybe headgasket), they tell you to follow their instructions, not OEM factory manual instructions... something like 80ft/lb + 90 degrees
have someone mark off a diagram of the head bolts so you dont miss a 80ft/lb torque or miss a 90 degree turn, i forgot at one point where i was, so threw out a head gasket and set of bolts
