Nearing the end of last year I installed a Lincoln v12 in a '39 L.Z Coupe. The engine is bored .060 over 2 7/8 and I used Egge pistons also Hogan heads. The pistons did not have the Ford dome, they were more angled to the top center. I told the manufacturer about this and they agreed. I don't think it would work if too much material was taken off stock heads. I purchased some Hogan heads unmachined and I machined them taking about 3/16 off casting surface. With a cutter using same piston profile, plunged to form that part of the combustion chamber. Clearance above piston with gasket is .053.

I think with those pistons, or the ones that I bought, may not work with stock heads. I will try to locate some pictures of the heads and send them tomorrow.
