CHEVROLET BB GEN 5&6 4.520 X . 072 ICS TITAN COPPER HD GSKT

The SCE Gaskets S145272 is a set of ICS Titan copper head gaskets designed for Chevrolet Gen 5 and Gen VI 7.4L Big Block engines. These gaskets feature a 4.520 in. bore and a compressed thickness of 0.072 in. They are constructed from copper and incorporate patented integral combustion and coolant seals that eliminate the need for additional sealants.

The design includes fluid seals bonded to both sides and offset for optimal sealing, as well as built-in combustion seals that serve as an alternative to O-ringed blocks or heads. The gasket body is split at the bore opening to accommodate a stainless wire O-ring for a primary seal, with upper and lower flanges providing a secondary combustion pressure seal. These head gaskets are recommended for naturally aspirated racing engines and are suitable for medium-to-heavy turbocharged, blown, or nitrous-injected applications.
