340 Cam, rocker, valve spring questions

It will be street 98 percent of the time. But want it drivable but as hot as I can get it within reason and be drivable, don’t care about gas milage ect as it’s not going to be a main mode of transportation, thinking a manual VB 904, not sure on stall yet as I have a line on a converter but may be to hot for a street car, think it was 4500/4900 something like that, and the gears I will run for now are to hot and will prob try to trade center sections at some point, can’t remember exactly but they were high 4’s low 5’s, what do most cut iron heads to eslitg 500lift?
