Okay, I know this is going fifty-eleven thousand directions...but...

We have a B&M supercharged 1972 Dodge Dart. It's basically got a stock long block 1974 360 with 60,000 miles on it that has a SpeedPro (I think it is) .429" lift camshaft and a roller timing set in. Currently the supercharger is sitting on a Holley Street Dominator aluminum intake manifold that I milled the carburator flange flat on for the supercharger. It has an Acell Super Coil and a Holley 750 cfm double pumper carburetor.
The car runs great/strong but I've been thinking about a head swap since I have a set of ready to go 2.02" J heads sitting here collecting dust.
My original intent was to just swap the heads and be done.
Lately I've been wondering about valve sizes.
Would it be beneficial to run the larger 2.08" intake valve?
What about the larger 1.625" or 1.650" exhaust valve?
Eventually I'll be going to a larger camshaft, though nothing crazy. Something with ~.480" lift.
Should I just stick the 2.02" heads on there or stuff larger valves in another set of heads?

Will the big block 2.08" valves work in the small block heads (length)?

In a factory casting head can you fit 2.08" (I) & 1.650" (E) valves?
