IF IT WAS MY ENGINE ID USE something similar to THESE,(PROBABLY A DIFFERENT PART NUMBER BUT THE PURE COPPER .021 THICK GASKET) yes IM FULLY AWARE it says you require (O-RINGS) IM using them now on my 383 without (O-RINGS) and have been very successfully for over 10 years
ID CALL AND SUGGEST YOU HAVE A LONG TALK WITH THE SCE TECH GUYS BEFORE ORDERING, but IVE found the gaskets to work great installed wet with a coat of copper spray gasket sealer,here is SCEs info

IVE had ZERO problems installing those solid copper head gaskets,or failures WITHOUT O-RINGS, if your not comfortable using them that's fine, the steel shim gaskets are cheaper and work really well.on steel heads,, provided they will give decent quench distances

steel head gaskets won,t work correctly on aluminum heads simply because aluminum being significantly softer , will indent and loose clamping force over time, you will need to use a head gasket that's designed for aluminum, Id suggest contacting SCE, and FELPRO to ask their advice, IVE never had the slightest problem with the thin copper head gaskets used without the o-rings but unless the heads and deck on the block are perfectly flat you could have, so your a bit safer going with the standard gasket designs
SUMMIT RACING,BRODIX, DART,or AIR FLOW RESEARCH TECH GUYS MIGHT ALSO HELP, but keep in mind you want to try for a .038-.044 quench distance

ID suggest trying for a MIMIMUM of .038-.044 on a 496 BBC for quench as the long stroke bbc, or any BBC run over about 6000rpm with a 4" or longer stroke) tends to allow the quench clearance distance to tighten up a bit at high rpms, as parts stretch under stress/inertial loads
