What is the primary purpose of head bolts?

Head bolts are critical for securing the cylinder heads to the engine block. They provide the necessary clamping force to create a seal between the head gasket and the block, preventing combustion gases from escaping and coolant or oil from entering the combustion chambers.

Why do the bolt heads have a reduced diameter?

The reduced diameter bolt heads are a practical design feature. They often allow access for re-torquing the cylinder heads without needing to remove other components like the valve train, which can simplify maintenance and assembly.

Are washers included with this kit?

Yes, this Edelbrock head bolt kit includes hardened and parallel-ground washers. These ensure a proper, even surface for the bolt heads to seat against, helping to distribute the clamping load effectively.

Product Details

This is the Edelbrock #8553 head bolt kit, designed for 1969-96 Ford 351 Windsor (5.8L) small-block V8 engines. If you're rebuilding the top end of your engine, especially with Edelbrock cylinder heads, these bolts are a solid choice to ensure everything stays securely in place. They are built to handle the clamping forces needed for proper engine operation.

These bolts are cold-formed for molecular integrity and heat-treated before thread rolling and machining, giving them a strong foundation. They're rated at 170,000 psi, which is a notable strength for head bolts. A practical detail is the reduced diameter bolt heads; this design often means you won't have to remove valve train components just to re-torque the cylinder heads, which can save you a good bit of time during assembly or maintenance.

The kit includes hardened and parallel-ground washers, ensuring a flat, even surface for the bolt heads to seat against. This attention to detail helps distribute the clamping load properly across the cylinder head deck.
