WHEN I WAS RUNNING " the gasket king company limited ", I had cylinder head gaskets for a couple of MASON MOTORS engine's.
That little motor fit quite a few " assembled cars ". I don't have my books available any more , as they, the application books got sold with the sale of the inventory , to Olsons gaskets in Port Orchard WA.
Your most likely not going to find a buyer for the motor in stated time period of 2 weeks. I only ever sold one NOS head gasket in the 16 years I was doing it. Olson should have got some from me.
