Depends on different things/situations ... most times any stock gasket is fine, some even use 2 in case of having many leaks and warpage on manifold from heat expansion, some even use high heat rtv as well.
Best thing is buy new studs as well and just over firm spanner tight, don’t worry about torque specs, run engine and check later and re tighten slightly to be sure no leaks., new hardened bolts will do the rest.
Also put some copper lube on studs to prevent seizing/rusting/loosening up from extreme heat is a necessity, so you can take them off if you have to later without breaking any of in the head.
Copper Lube is different to the Loctite sheet blue/red thread locker which shouldn’t be used.
