Are you going to use the one piece metal gasket and valley pan as the factory used, or are you going to a solid valley cover and separate intake paper or composite gaskets? Those don't look like they were enlarged to max wedge size, so I say you just need to trim the gaskets open to fit. I have no experience with the actual stealth heads, but it's common to adjust gasket openings after heads have been opened up.

I did not end up getting the max wedge ports. I have a separate valley pan that I got from 440 Source. I measured the ports and they are all 1.27"x2.32". There are no gaskets with those dimensions specifically so I was starting to wonder if I was just going to have to break down and cut on a set of gaskets. Not a real big deal to me, but was making sure I wasn't wasting time if a direct set was available.
