Any of the composite gaskets would be fine for your aluminum intake (if you can locate them). Do not use steel. Those are meant for cast iron intakes. I bought several NOS Offenhauser Poly intake gaskets from a seller on Ebay who seems to be a regular seller. I suggest you keep checking there.
Thanks!...yep aware the steel gaskets are for cast iron intakes, there's one cottage mfg making composites with a steel core, not to sure what to make on them, they come in at .050 thick with a silicone print-o-seal, I've scanned Ebay but no luck so far.... would prefer mfg recommended gaskets
