An N.A. cylinder head's bolt patterns will not allow an SC intake and exhaust manifold to fit. So basically you need an SC head on your NA block.
The N.A.'s block internals could be beefed up to SC standards. The key and critical component would be lower compression (SC) pistons. Another approach to reduce compression ratio would be to fit in a custom thick headgasket. However, that would change the deck height, which would require adjustable cam gears to allow the change in deck height to work.
Silvertop pistons and rods are lighter versions of ordinary N.A. pistons and rods. Neither would last long in a supercharged regime.
I was glad to read that your post was not well worded, and that in fact you weren't thinking about doing the unthinkable. Putting an NA engine into an SC car. I'll send out a recall order to the outraged, torch carrying villagers immediately.
Best of Luck
