Cometic gaskets can send you what you need or super close to it.
Your looking for a .045 quench, with a piston sitting in the hole .010, your looking at a .035 head gasket. See if you can find that thickness and with the proper cylinder bore size. If you can’t find one, call Cometic.
Cometic makes a #C-5457-036 (4.125" bore x .036 thick) for a reference.
