SBC Titan Copper Head Gasket 4.155 x .043

The SBC Titan Copper Head Gasket 4.155 x .043 from SCE Gaskets is purpose-built for small-block Chevrolet engines seeking maximum reliability and thermal stability under high-performance conditions. Whether you're rebuilding a street engine, track-prepped vehicle, or boost-assisted application, a quality head gasket is the foundation of any solid engine package. This gasket bridges the cylinder head and block, sealing combustion pressure while maintaining critical coolant and oil passages—failure here cascades into catastrophic engine damage.

SCE's Titan line employs 100% virgin copper construction, a material choice that outperforms traditional compressed asbestos or modern composites in thermal conductivity and reusability. The 4.155-inch bore diameter matches small-block Chevrolet specifications precisely, while the .043-inch compressed thickness ensures proper clamp load without excessive block/head surface prep. Copper gaskets conform to micro-surface irregularities better than steel-core designs, reduce hot-spot formation around the combustion chamber, and withstand repeated heating cycles—critical for forced-induction engines or high-RPM builds where temperature swings exceed 300°F.

This gasket suits SBC variants from 283ci through 406ci displacements and is ideal for nitrous, supercharger, or naturally aspirated applications running boost levels up to 12 psi reliably. During installation, torque cylinder head bolts to specification in the correct sequence—copper gaskets demand proper clamping force to seal effectively. Many experienced builders prefer copper for longevity and reusability; if you plan future head removal for cam upgrades or valve work, this gasket survives multiple cycles without degradation. Pair with quality ARP head studs and quality fastener prep for best results.
