Heli-Coil Spark Plug Threaded Inserts

Repair stripped or damaged spark plug threads! Heli-Coil spark plug threaded inserts are manufactured from 18-8 round stainless steel wire formed into a 60 degree diamond-shaped wire. This cold-worked wire (which has a tensile strength of 200,000 psi) is wound into a helical coil with a driving tang and notch—to remove the tang after the insert is screwed into the Heli-Coil tapped hole. In their free state, the inserts are larger in diameter than the tapped hole. Once installed, each insert assumes the configuration of the tapped hole. The resulting outward spring-like action anchors the inserts in place. The Heli-Coil spark plug inserts become an integral part of the cylinder head, providing high-strength threads which exceed in surface smoothness, hardness, and accuracy than any other threads.

Reid Racing Super Hydra 400 Transmission Cases

Chevrolet Performance Bowtie Aluminum Cylinder Heads

Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in.
