Another great vintage listing from Falcon Classic! This listing is for a BEST Gasket complete/full gasket set for 1937-54 Chrysler and DeSoto models and 1937-68 Dodge truck models using a 218ci, 228ci, 237ci, 241ci, 251ci, or 265ci flathead 6-cylinder engine with a 25" overall length cylinder head. P/N RS510C/4164. 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!
