I would buy a one piece Fel Pro oil pan gasket if you have a 1977-'85 SBC donor motor. Fel-Pro part number OS 34510T and follow the directions. I am still looking for the number for the thin gasket front pan for the earlier motors. The one piece rear main seal of course is a stock Fel-Pro gasket as all of the gaskets available are one piece with the one piece rear main seal block. Use Fel-Pro part number OS-34509T for a 1957-74 SBC 262-400.
