Where to find thin .030 or less head gaskets for 4.070 bore

Get ahold of Cometic. They will make you anything you want but they are not cheap. Keep in mind that you will need a minumum of .035 piston to head clearance, so if you are a building a stroker, you may as well have it decked for zero deck and use a .035 to .040 gasket.

P4120094 with the measured 4.125" bore will put me at my target compression. I need a set of head gaskets anyway. Cometic is overkill for what I'm doing.
