Don't read if you're close minded

On the Dom he used an HVH 4 hole tapered 4150-4500 adapter and he said he’s never seen it loose power. It’s usually worth 10. So maybe it’s more the spacer than the carb.

Agreed. Imo, the test is,only semi valid. Better would be to use similar manifolds dedicated to the carb of choice...... or best, a manifold for a dominator that has stud holes for a 4150 too, so both can be run on the SAME manifold.... without an adaptor or spacer.. or a 4150 with slots in the baseplate for a dummy intake.
(Note, if I make a stupid comment here, it's cause I haven't read this whole thread yet... but I will!)
