... could it be used for some "creative" intake plenum rework, such as what was done w/ welding & grinding by Hughes below to modify a spread-bore intake flange into a square-bore design?

I've been using Belzona products since the '80s. They were expensive then, hate to see the prices now. Their lines have changed so whatever i used back then is outdated.
Nice thing about Belzona is the technical service you can get just by asking.
It's an extremely high grade epoxy product with different formulations for different uses. In the '80s it cost more than $150 per kg. I had a friend who patched a big hole in an Olds 455 block with some stuff he pirated out of work. It did the job, let him get the jet boat back in the water.

I would go on the Website, then call a tech rep and start asking questions.

Brad I am just throwing this out there but by time the second intake was ported correctly how close would it be size wise to the first picture? Why don't you play sizing a carb base gasket to see if you could just square it up or go to a dominater flange size.

Good stuff. Expensive, but I can't think of anything better for what you want to do with it. Prep is king when you do stuff like that. Surface needs to be CLEAN and rough for best adhesion. You can even drill and tap the stuff in some non-critical applications where you can't use a helicoil or thread insert.
