RS521G

Another great vintage listing from Internal Engine Parts  This listing is for a BEST Gasket complete/full gasket set for 1949-53 Ford and Mercury passenger car models and 1948-53 Ford truck models using the 239ci or 255ci flathead V-8 engine with distributor mounted at perpendicular angle to the camshaft. P/N RS521G; head gasket bore is 3.295". We offer "big bore" head gaskets for large overbored blocks.

This gasket set is for late-design flathead V-8 engines which have the distributor mounted at a perpendicular angle to the camshaft; compared to early-design where the distributor is driven directly off the forward end of the camshaft.

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

GraphTite™ cylinder head gaskets consist of Kevlar reinforced graphite facing material mechanically bonded to both sides of a perforated steel core. This modern engineered, high-performance material is rated to a temperature of 1400°-F. Steel fire rings are installed in the combustion chamber areas of the gasket.

GraphTite™ head gaskets have superb sealing characteristics, excellent torque retention, and hold up to the punishment dished out by high-performance engines – high quality all the way. This gasket might be overkill for cruiser engines, but so what... extra performance never hurts!

TECH NOTE: When installing GraphTite™ head gaskets, use a spray-on sealant like K & W Copper Coat or Permatex Copper Spray-A-Gasket and always re-torque... no short-cuts.
