if you're gonna go supercharged your motor should be fine. if you want to get some better performance, i'd get a hold of LC and order some forged pistons though. stock cast ones won't take a lot of boost, and stock compression for '81-84 is 9.0:1. i'd bump it down to at least 8.4:1 depending on how much boost you want to run.
on the other hand, you could always find a 20R bottom end and put your 22R head on it. stock compression on a 20R is 8.4:1 and the combustion chamber size is similar on the 20R and '81-84 22R. only downside is that the 20R pistons are still cast(though you could probably get KB pistons for it) and you lose 200CC of displacement.
LC Cam, 22block, 20R head
not for boost tho, just put regular efi pistons in it then run 20 psi boost
