This might be possable if you want to redome the heads the transfer area determines the CR and this area is deaper in the Merc. and 8RT heads. You might try angle milling, However you'll start running into the thermostat housing after .050-060" Seems like allot of work. Just to reolace the EAB head. I also mill them to give .040-050" piston clearance. After you do all this you'll have to clearance for the valves especially if your running a high lift cam. Building an engine takes some thought.
