SBM Titan Copper Head Gasket RH 4.155 x .043

The SBM Titan Copper Head Gasket RH 4.155 x .043 from SCE Gaskets is purpose-built for serious Small Block Mopar engine builders and performance enthusiasts who demand bulletproof combustion sealing under extreme conditions. This right-hand gasket is engineered for high-horsepower applications where stock gaskets fail—turbo builds, nitrous systems, forced induction conversions, and high-compression street/strip engines all rely on the superior heat dissipation and clamping force retention that copper construction delivers. Whether you're freshening a 340, 360, or modern Mopar stroker, this gasket prevents compression leakage, coolant weeping, and catastrophic head gasket failure that can cost thousands in engine damage.

Copper head gaskets are the gold standard in racing and modified engine applications because copper conducts heat away from the combustion chamber faster than traditional composite materials, reducing hot spots and detonation risk. The 4.155-inch bore specification and .043-inch compressed thickness match OEM Small Block Mopar cylinder head dimensions precisely, ensuring zero guesswork during gasket selection. The right-hand designation (RH) indicates this gasket is cut for the passenger-side cylinder head, with locating dowels and embossed fire rings that grip both the block and head deck under boost, nitrous charge, or high cylinder pressure—critical for engines running 10:1+ compression ratios or forced induction. SCE's proprietary copper blend resists corrosion and maintains clamp load across extended heat cycles, unlike softer gasket materials that creep and lose sealing integrity.

This gasket is essential for any Mopar small-block rebuild exceeding 400 horsepower or incorporating forced induction, turbocharging, or nitrous oxide systems. Installation requires proper head bolt torque sequencing (typically 65–75 ft-lbs on production engines, higher on race blocks) and a clean, flat deck surface—wire brush the block and heads before assembly to remove old gasket material and carbon buildup. Pair this right-hand gasket with matching left-hand and intake gaskets from SCE for complete engine sealing confidence. Professional installers and weekend warriors alike trust copper head gaskets when stock components cannot survive the power levels and thermal stress of modified Mopar engines.
