SBF ISC Titan Copper Hd Gasket LH 4.155 x .050

The SBF ISC Titan Copper Head Gasket LH 4.155 x .050 from SCE Gaskets is a premium-grade cylinder head gasket engineered for small-block Ford engines running high-compression builds and aggressive ignition timing. Designed specifically for left-hand applications, this gasket bridges the critical seal between your cylinder head and block—the most thermally and mechanically demanding interface in any engine. Whether you're building a street performance engine, a weekend drag competitor, or restoring a classic Ford with modern internals, this gasket handles the thermal cycling and combustion pressures that stock gaskets cannot.

SCE's Titan Copper construction combines a pure copper core with precision engineering to deliver superior heat transfer and sealing integrity across the entire bore range. The .050-inch thickness and 4.155-inch bore diameter are optimized for SBF (small-block Ford) ISC architecture, providing consistent clamping load distribution and minimum deformation under sustained high RPM and elevated combustion temperatures. The copper composition significantly outperforms traditional composite gaskets in thermal conductivity, helping prevent hot spots and reducing the risk of detonation in tuned engines—a critical advantage when running 93-octane fuel or higher compression ratios above 10:1.

This left-hand gasket is the correct choice for SBF cylinder head applications requiring driver-side sealing on dual-gasket or split-design configurations. It's ideal for engine builders upgrading from factory Ford gaskets to gain reliability under boost, high timing advance, or naturally aspirated power adders. Installation requires proper head bolt torque sequencing and a clean, smooth deck surface for optimal sealing—follow your build manual's specification for your particular SBF block variant. SCE Gaskets' reputation for durability makes this component a trusted choice among professional engine shops and serious enthusiast builds nationwide.
