Speedmaster PCE279.1005 BBC 454 12-Point Head Stud Kit for PCE Cylinder Heads

The Speedmaster PCE279.1005 head stud kit is engineered specifically for Chevy Big Block 454 engines using PCE cylinder heads with 8-inch long studs. These precision-engineered fasteners provide superior clamping force and reliability compared to traditional head bolts, making them ideal for high-performance and racing applications.

Premium Construction:

• Manufactured from aircraft-quality 8740 chromoly steel for exceptional strength
• Cold-forged construction ensures molecular integrity and durability
• Heat-treated prior to thread rolling and machining for maximum performance
• Rated at 190,000 PSI tensile strength for extreme applications
• 12-point nut design allows for precise torque application in tight spaces

Complete Kit Includes:

• High-strength head studs (8-inch long configuration)
• 12-point chromoly nuts for easy installation
• Hardened parallel washers for even load distribution
• All components needed for complete cylinder head installation

The hardened parallel washers ensure accurate torque readings and even clamping pressure across the head gasket surface, reducing the risk of head gasket failure. The 12-point nut design provides more engagement points than standard 6-point nuts, allowing for easier installation and removal while reducing the risk of rounding. Ideal for street performance, drag racing, and other high-stress applications where cylinder head retention is critical.
