Series 2 L67 (SC):
LIM bolts: FSM states 13ft lbs, that is with nylon gaskets. I use 15ft lbs with aluminum gaskets in this position. Work your way from the inside bolts to the outside bolts in a criss cross fashion.
UIM/SC bolts: FSM states 17ft lbs.
Series 2 L36 (NA):
LIM bolts: Some FSM'* are incorrect (96/97) and say 89 inch lbs. That is the torque for the UIM bolts. The correct spec on the LIM bolts is 13ft lbs. Like the L67 if using the aluminum gaskets in this position I automatically use 15ft lbs. Work your way from the inside bolts to the outside bolts in a criss cross fashion.
UIM bolts: These are tricky, the FSM states to torque in steps. Use ~40in lbs, then 60, 70, 80, 89. Watch the UIM near the bolt as you torque it, go very slow and watch all of these very closely. if the manifold appears white and looks like it is about to break, stop torquing that bolt and continue on to the next. This is fairly common with the nylon manifold.
As for RTV, I buy only Permatex Ultra Copper RTV as it will work in all fluids and temperature ranges. Put a dab in the corners where the head meets the block, put the gaskets on and then put another dab in each corner on top of the gaskets. Black rtv is also good, I just happen to buy only the one tube because the goop drawer was overfull with all the various colors.
00 Regal GS: All kinds of cool stuff.
