WHICH head gaskets are you going to use?
The common ones are .040 thick composition gaskets. They're a disaster. You'll destroy whatever quench/squish the engine has, which was probably pretty meager to begin with.
GM and the aftermarket sell .028 composition gaskets, they were common on '90s engines. Better. Not optimum.
Given any choice, I'd use .015 steel-shim gaskets IF (big IF) the block and head gasket surfaces are FLAT and SMOOTH. These come with a rubber-ish coating to help them seal.

Don't forget to buy some Loctite/Permatex 592 sealant for the head bolts. Use the SPECIAL TBI intake manifold gaskets if you're using the OEM TBI intake manifold.
