440Source stealth heads

I have never used the Stealth head on a build. I did however order a single Stealth head in June 2010 for testing purposes. It might be easiest to refer you to here:

Notice on the second page, in Feb, 2012, we had ported the Stealths to 346 cfm. The castings still seemed to be of good quality at that level of porting and probably could go into the 350 cfm range like we have with the Edelbrock RPM heads.

As to the Super Stealths, I have not yet been able to test one. It does however state on their website that it can use factory manifolds but will require .650" offset rockers. If I still lived in Lancaster, CA I would just slip over to their place on Ave J-5 and have a look at the heads.
