NECK PORTING LS6 intake?
If it were me, I would take it to a place that does
plastic welding and have it built up. I believe that
the manifold is Zytel nylon and somebody in that
line of business ought to be able to get you (say)
a 1/4" slab plastic-welded onto the face (easiest
way to have a planar mounting surface) and build
enough on the side to take the hog-out.
You might even go find a plastic welding kit and
go at it yourself, but that might be a limited-use
tool once you're done, and you still have to go
chase the plastic stock & filler rods etc.
