Pistons aren't necessary unless you have to as part of a rebore or something?
If you do need them, go with stock replacements (appropriate bore size) forged (just for the added durability). Nothing fancy needed really.
The heads are one of the bigger factors as far as increasing performance. It's all about getting more air/fuel into the combustion process. Turbo, good heads, (in your case, the 84/85 intake is pretty constricted too, so porting that becomes important), good exhaust. Those make power.
Crank, pistons, block, etc. are more part of the durability factor than making power.

Might contact Champion (same place that does heads...). Even if they won't, they might point you to a good guy...
