I stumbled across this company, Gaskets-to-Go, who can make any gasket with no tooling, setup costs, or best of all no MINIMUM ORDER. Perhaps someone has some free time and can scan a gasket and go through the quote process to determine what the cost would be for a true MLS, multi-layer-steel, head gasket? The Ajusa is great, but it would be excellent if we had an MLS gasket option without composite materials.   http://www.gasketstogo.com/
