I would get a drimal and clean up that corrosion^ maybe smooth it out a little.

The black is just accumulated layers of unburnt hydrocarbons that repeatedly got cooked over the many years of the manifold's life. I'll be spraying the whole insides with engine degreaser and hosing it out. Can't get inside there with a Dremel. The hole is way too small and the runners are too deep inside the plenum.

Saw this pic of a thick custom made intake flange on the Micro forum...

I tried tapping with ball peen hammer on the inside of the runner to flare the opening with some success. But instead of risking denting or deforming the runners, a thick flange like this one with a few extra beads of weld on the misaligned areas will provide plenty of room to smooth the transition from the inside with a grinder between the runners and the engine intakes.
