From what I'm reading, when it gets right down to it the 273 performers
The "best"running the basics............. 3 C's
Cam carb and compression
As long as I got the 4bbl pistons a a small chamber head(with a littlie work done)
And a mech cam under .530 all shound good?

Nope. The 4bbl pistons will not generate the static compression especially given any available head gasket nor is it tall enough or of the right configuration to generate an effective quench.
While I agree with some of what Dave notes in terms of head theory - most of it IMO is overly concerned with relatively small details that don't add up to more power. You will get more power from the larger valve, especially given the rpm range you're contemplating. If you're really concerned about the shrouding then you can notch the bore but I'd rather not bother. Just my opinon of course.
