Also do they make a gm performance replacement manifold that is legal ? Or only the gm stock original manifold

Rory, to the best of my knowledge, there is no legal replacement manifold. I sold the last one I had back in February. They usually bring around $400 to $500. The guy who bought mine is building a stocker.

You can use the spacers in a production block, a Dart block, or a BowTie block. I would not use a production block, as Dwight said, you're money ahead using the better blocks. They last longer, stay fresh longer, and make more power. You spend a lot of money on the blueprinting operations on a production block that are not needed on a race block.
