This listing is for a BEST Gasket complete/full gasket set with copper head gaskets for 1938-42 Ford passenger cars and 1938-47 Ford trucks with the 221ci "24-stud" flathead V-8 engine.

Part Number RS505C.

This engine is referred to as a "24-stud" because each head requires 24 studs to fasten to engine block. Also to help with identification, the 221ci has a 3.062" standard cylinder bore; compared to the 3.187" standard bore of the 239ci flathead.

BEST Gasket is the leading name in sealing performance in the restoration industry. Image shown is an actual factory supplied picture showing set contents.

Best copper cylinder head gaskets consist of two outer sheets of a generously thick .010" copper and a low-density graphite “filler” sheet. This high-quality graphite sheet is superior to asbestos, which was used in the old days, and far superior to the non-asbestos materials found in other manufacturers' modern copper head gaskets. Excellent torque retention is achieved by using superior materials. Best copper gaskets are definitely “old-school” but with a modern flair for better performance. They are such works of art, we almost hate to sell them!

ENGINE PARTS CENTERS TECH NOTE: When installing a Best copper head gasket, use a spray-on sealant like K&W Copper Coat or Permatex Copper Spray-A-Gasket and always re-torque; no short-cuts.
