Exhuast Gasket SBC 23 Degree Dart Platinum

The Exhaust Gasket SBC 23 Degree Dart Platinum is a precision-engineered header gasket designed specifically for small-block Chevrolet engines paired with Dart Platinum cylinder heads. This gasket is essential for builders and performance enthusiasts who require a reliable seal between custom headers and modern aftermarket heads with a 23-degree valve angle.

Proper exhaust sealing at the header flange is critical, as even small leaks can rob horsepower and introduce exhaust noise. Manufactured to withstand extreme exhaust temperatures and thermal cycling, this gasket ensures a perfect gasket-to-flange interface that eliminates hot spots and micro-leaks common with mismatched gasket geometry. Its design resists creep and maintains clamp load retention through countless heat cycles, making it suitable for both street engines and race applications.

This gasket is ideal for small-block Chevrolet engine builders upgrading to Dart Platinum heads, whether for street performance or bracket racing. Installation requires proper header bolt sequencing to ensure optimal performance and sealing integrity.
