Diamond domes

Diamond has a pretty usable domed 427 piston that we can tweak for other uses. The dome just barely tags a factory MR chamber in the two spots where it closes in around the deep side - just a couple inward facing points in the gasket face shape - most chambers that have been worked over will not have any issue at all. It works OK on Ed heads, and can work on most anything within ten minutes with a grinder and a light touch. I'll often test assemble without a head gasket and painting the piston dome with a magic marker - any contact will show up instantly as a bright silver mark. guarantees at least .040 clearance everywhere that way.
