BBC Dart Big Chief Intake Gasket .06in Thic

The FEL-PRO BBC Dart Big Chief Intake Gasket .06in Thick (MPN 1298) is a precision-engineered composite gasket designed specifically for big block Chevy engines running Dart Big Chief cylinder heads. This gasket seals the critical interface between your intake manifold and cylinder heads, preventing coolant and combustion chamber leakage that can degrade performance and cause engine damage. Whether you're building a street engine, race platform, or restoring a classic BBC powerplant, a quality intake gasket is non-negotiable for reliable, leak-free operation.

This FEL-PRO gasket features a 0.06-inch composite construction with rectangular port dimensions of 1.86 x 2.46 inches, engineered to match Dart Big Chief head specifications precisely. The composite material provides superior heat and chemical resistance compared to traditional cork or rubber gaskets, maintaining its seal integrity across wide temperature swings typical in high-output engines. At just 0.53 lbs and compact 8.8 x 0.6 x 26.25-inch packaging, installation is straightforward—simply clean both mating surfaces thoroughly, apply a light bead of gasket sealer if desired, and torque to factory specifications using a crosshatch pattern.

Mechanics and engine builders trust FEL-PRO gaskets for their consistency and durability in both stock and modified applications. This gasket is essential when assembling new Dart Big Chief heads, replacing a leaking original gasket, or rebuilding an existing BBC engine. Proper gasket selection prevents expensive coolant loss, oil contamination, and intake manifold vacuum leaks that compromise carburetor tuning and EFI calibration. Keep a spare on hand for your shop—it's a critical wear item that ensures every BBC build starts right.
