How difficult is it to get a decomp plate made up, then welded to the head? Effectively making the head taller, but no need for 2 gaskets. Can't see it being perfect without welding round each oil/waterway though, then machining the holes to right size again.
you dont have to weld the decomp plate you bond it to the head,then fit your headgaskets as normal, say if you have a de comp plate at 2mm it would drop the compression ratio to around 8-1 on a 2.0 zetec with a decent turbo you could run about 15 psi and around 240-50hp
