Product Details

The Speedmaster PCE279.1003 head bolt kit is engineered for Chevy Small Block 350 engines requiring extended bolt length. These premium fasteners feature 1/4-inch additional length compared to standard bolts, making them ideal for applications with thicker head gaskets, milled heads, or aftermarket aluminum cylinder heads.

Key Features:

  • Constructed from aircraft-grade 8740 chromoly steel for maximum strength and durability
  • Cold-forged manufacturing process ensures molecular integrity and uniform strength throughout
  • Heat-treated prior to thread rolling and final machining for optimal hardness
  • Rated at 190,000 PSI tensile strength for superior clamping force
  • Extended length design accommodates modified deck heights and gasket combinations
  • Precision rolled threads reduce stress risers and improve fatigue resistance

This complete kit provides all the fasteners needed to secure both cylinder heads on your SBC 350 engine. The chromoly construction and high tensile strength rating ensure reliable head gasket sealing even under high boost or compression applications, making these bolts a smart upgrade for performance and racing engines.
