Sorry one of techinspector1's posts got split out by accident so here is a copy of what he posted. Hey Danny, keep your shirt on buddy. Sometimes I have other things to do, but when I get time, I'm always be pleased to run the DynoSim for you guys.
I'm gonna change some parts around, because foolin' with this toy for a while now, I've developed a feel for what works and what doesn't. I kept your heads, but changed the pistons to KB193. They make the same 9.6 SCR that the others you listed do, but the rings are 5/64" instead of 1/16". Better for a street motor. I also changed the cam to a little tamer model. The one you had listed wouldn't make enough cylinder pressure with the 9.6 SCR.
355 Chevy, 9.60:1 SCR w/KB193 12cc dish pistons
Patriot 195's w/64cc chambers
Performer RPM intake w/750 carb of your choice
CompCams XE274H (This is a flat tappet cam. Personally, I'd use a roller, but with these specs)
274/286, 230/236, 110, .519/.522 w/1.6 rockers, installed 1* retarded.

Hey, 477/470 from a mild 355 is not to be sneezed at.
