I might have .050 left before the gasket(stock) edge. Matches pretty well with my 1 5/8" headers^^^ SMH 🙂 ^^^ Nice to see Mike breakin in new members right.
Less floor work (kinda a waste of time), but you didn't hurt them to run the 6000 that your cam wants to run. Don'twaster your time gasket matching, has the same kind of result as hogging out the floor unless you can carry the gasket dimension to the radius.
