Pat's wrong on this one. That didn't come from me. He probably thinks I left the LIM on the engine, but the one on there was cut for the IC core and came off before you picked it up.

The early Gen V manifolds has the recessed area for coolant o-rings in the gasket (like a Gen 3 gasket) and the newer style of manifold had a flat top for the aluminum Gen V gasket.

Either way, I'd suggest drilling, tapping and using 1/4" npt plugs on the coolant ports. Then take off the side cover of the LIM and port out the coolant passage from rear to front.
