SpeedFactory Racing Cylinder Extreme-Duty Head Stud Kits

The SpeedFactory Racing cylinder extreme-duty head stud kits are engineered for high-performance engines, specifically to prevent cylinder head lift and blown head gaskets in high-boost (30+ psi) drag racing applications. Made from ultra-strong L19 material, these studs offer more clamping force and strength than standard 8740 chromoly studs, ensuring engine reliability. Each kit includes forged nuts and washers designed to distribute clamping loads evenly across the engine block.

Key features:

* High-strength (260,000 psi tensile strength) material keeps the cylinder head securely clamped to the engine block under extreme combustion pressures
* Designed for engines producing high boost (typically 30 psi) to help prevent gasket failures
* Extreme Material Strength—L19 material outperforms standard 8740 chromoly steel, providing superior clamping force
* Easy Installation—head studs feature a hex broach on the top, allowing for simple installation without removing the engine
* Superior Load Distribution—these kits include oversized nuts to distribute load more evenly
* They are a direct drop-in replacement for OEM head bolts
