I can tell you there is a reason some gaskets are $20 a pr and some are $50 each. I can't give you part numbers but my advice is stay on the expensive side. Too much work to have to do it twice.
Always had good luck with Fel Pro gaskets. You'll have to do some research to find the right part for your application. There is a special combustion ring for aluminum heads. Its called pre-compressed or something like that. You also have to get the right bore diameter.
"Forged in the fires of high performance engines, Fel-Pro performance head gaskets are quite literally created to tame the fiery combustion chambers of up to 1,000 hp engines. Reinforced with KEVLAR® fiber and engineered to give you a perfect seal that can withstand combustion pressures of 1,500 to 3,000 psi, these gaskets are bred for high performance. They have a conformable anti-stick coating—and are constructed with pre-flattened copper or steel rings to make these gaskets easy to install, while also giving them the strength to tame your beastly power plant. Their anti-stick coating ensures easy removal and cleanup on frequent rebuilds, but they also aid in micro-sealing minor surface irregularities. When rebuilding your engine, use the parts you wish were in it to begin with. Put a set of these Fel-Pro performance head gaskets in that engine--not only to help it perform better today, but to make your next engine project that much easier."

That would be a good gasket for a zero decked block.
do you put gaskets on naked or do you spay them with copper paint, this may be old school? thanks
Follow the manufacturers instructions. Any modern head gaskets I have used has some sort of coating on them, even MLS, meaning you put them on dry. The only time I have ever used a spray was when I used a flat sheet copper gasket on a custom 4 cylinder 20+ years ago and when, in desperation, I had to reuse an original MLS gasket when no new ones were available (Taurus SHO V8).

My thinking is that the block surface may not be smooth enough to seal properly with just the gasket so this is kinda like insurance. It may not even be necessary but it's a lotta work to replace the head gaskets. I haven't had a leak yet on either aluminum head to cast iron block, and it's been about 6 years and 12000 miles.
