fabricate aluminium header flange gasket

Fabricating and welding a new steel header flange sounds good but that could take all day or 2. The embossed copper header gaskets look great but how can I be sure the copper oval will fit the oval 88650 headers? If I fabricate a header flange gasket from 3/16" 6061-T6 Aluminum (Brinell hardness of 95 vs 38 for lead and around 120 for steel) will I need additional gaskets on both sides of the aluminum gasket?
