Copper Head Gaskets for Ford 351C, 351M, & 400 "Cleveland" Small Block Engines

Description

Two used copper head gaskets for Ford 351 Cleveland series small block engines (351C, 351M, & 400).
These 351C copper head gaskets were used once on one engine and are in great shape. They can easily be reused by either flipping them over so your block's O-rings imprint on the unused sides of the copper surface. Or by annealing them with a torch (using a rich/fat carburizing flame) to make the copper "dead-soft" again and then using either side of the gasket against your block's O-rings.
FYI, from my past experience the buyer will need to re-torque this style copper head gasket (before and after the 1st couple of heat/cool cycles) to fully embed the Stainless Steel O-ring wire into the soft copper surface. Also a good choice of sealer for the buyer to use is 3M's silicone sealer meant for "metal/aluminum" since it has aluminum in it. The 3M sealer worked best for me with this style copper head gasket to seal the water passages.
This sale only includes the copper head gaskets shown in the above pictures. Stainless Steel O-ring wire & 3M silicone sealer are NOT included in this sale.
