Porting & Welding LIM

Porting & Welding LIM
We've been gasket matching the UIM and LIM on an RE engine. The LIM intake gasket matches the engine ports extremely well, but matches the intake horribly. Were going to attempt to port the LIM to the gasket but are worried about running into the EGR (not sure if this term is correct) passages. Does anybody have experience with this? We are also throwing around the idea of welding up the EGR passages on the LIM to keep the exhaust from entering the intake and heating up the intake charge. Any experience with this or recommendations?

I welded the unused passages on both my UIM and LIM, removed the EGR passages (I had a lot of extra time), Extrudehoned, then polished. On the engine, I machined aluminum block-off plugs for the EGR ports in the rotor housings and locked them in place with roll pins (I'm using FD housings).
