Overall very decent build. I would port the intake for sure, go to thinner gasket/mill heads for more compression and run the offset BBC head dowels and slide the heads over .030 to get the intake valve off the wall. Probably 20-30hp in all of that and a lot of torque. Spin makes fantastic cams, the results show it.
