Here's how I do it.

Lets say you're matching the UIM to the LIM.

There are a few studs on the LIM so place the gasket over them. There should be little wiggle room but there will be some. If there is enough such that the gasket is interfering with the ports, you need to tape that gasket in place. But do this before you put a few bolts through the upper intake manifold and make sure the same thing doesn't occur.

Once you're satisfied that the gasket is in the right position and tapped off such that it won't move, assembly the sandwich. Take a small 3/32 or 1/16" drill bit and drill through the Upper intake mani, the gasket and into the LIM.

Remove upper intake.

Place drill bit through hole in gasket and into hole in LIM. Mark with whatever what needs to be ported.

Place drill bit through UIM, place gasket over drill bits, place gasket, UIM, and bits over LIM until bits fall into previously made holes on LIM.

Bolt UIM to LIM.

Remove drill bits.
