Help me sort my combo

When I first put this together in 98 I wanted to put a big block in and keep the power steering and power brakes, just as if it came from the factory like that. There weren't a lot of piston options available back then and I had to butterfly cut the pistons when I added the stealth heads because they changed the geometry just that much. Sure don't mind a new converter, never been a fan of the one in there. Thanks for the replies yall.
