BAE Copper Head Gasket 4.470 x .080

The BAE Copper Head Gasket 4.470 x .080 is designed for high-performance and racing applications where thermal management and durability are essential. This premium copper head gasket is ideal for builders and mechanics who are modifying engines, whether for naturally aspirated builds with higher compression ratios or boosted applications that require reliable sealing under extreme conditions.

Constructed from copper, this gasket excels in environments where cast-iron or aluminum blocks meet aftermarket heads, offering superior heat transfer and longevity compared to conventional materials. The .080-inch thickness and 4.470-inch bore diameter are precisely engineered to maintain a tight seal across multiple heat cycles while minimizing changes in combustion chamber volume. The copper material allows the gasket to conform to surface imperfections, ensuring a reliable seal even on used or ported surfaces.

Engine builders and mechanics favor BAE copper head gaskets for street/strip combinations, forced-induction platforms, and high-compression naturally aspirated engines where traditional gaskets may fail. This gasket is particularly beneficial for those running aggressive ignition timing or intercooled boost levels, making it a versatile choice for serious performance applications.
