Get a good gasket and some high temp silicone sealant, the cheap ones tend to leak a lot quicker especially into the plug recesses fragging your leads and plugs.
Use the silicone around the cam radii to ensure it does not leak

Torque the bolts down to get even compression exactly like a head and bobs your uncle

I always use some sort of lube on the inlet bolts or "dry bolts" just so they come off easier next time.
Worth having a new gasket for the TB and inlet or some gasket sheet to cut a new one, old ones either come off in one piece or two

While your there worth porting the TB, inlet and gaskets
