Speedmaster PCE279.1006 BBC 454 12-Point Head Studs 6.100" Length (8 Studs)

Speedmaster PCE279.1006 cylinder head studs are engineered for high-performance Chevy Big Block 454 engines requiring maximum clamping force and reliability. These 6.100-inch long head studs feature a 12-point design for precise torque application and are sold in a set of 8 studs.

Construction and Materials:

• Manufactured from aircraft-quality 8740 chromoly steel for superior tensile strength
• Cold-forged construction ensures molecular integrity and consistent grain structure
• Heat-treated prior to thread rolling and final machining
• Rated at 190,000 PSI tensile strength for extreme cylinder pressure applications
• 12-point head design allows finer torque adjustments in tight spaces

What's Included:

• 8 head studs (6.100" length)
• 12-point nuts for precise torque control
• Hardened parallel washers for even load distribution and accurate torque readings

These head studs provide significantly improved clamping force over standard head bolts, making them ideal for high-boost, high-compression, or nitrous oxide applications where head gasket sealing is critical. The 12-point nut design allows for 30-degree incremental adjustments compared to 60 degrees with standard 6-point designs.
