If keeping the FT is your short/med term solution.

I would agree that you now have the opportunity to source a proper supercharger friendly cam.

Gen V block will require the aftermarket link bar style lifters of course. Important to source quality roller lifters or you'll be in the same boat again.

What heads heads have got on the 502?

It is a gen 6 block . It was a complete gen V engine whit crack block du to bad winterized. And they rebuilt It on a gen6 block switching everyting on it. I dont know spec about head but i heard i have the good one

Looks like stock GM rect port heads with new valves.

To do the conversion, you will need:
Roller cam
Roller lifters
Roller rocker arms
New valve springs, retainers, locks
New pushrods--possibly will need to be made custom to length
ARP Rocker arm studs
Maybe a new timing chain set
Grind off the drip tabs on the inside of the valve covers to clear the roller rockers
