Why do I need a specific bolt kit for aluminum heads?

Aluminum heads are typically thicker than cast iron heads, and they require the use of hardened washers. This Edelbrock kit includes longer bolts to properly account for the combined thickness of the aluminum head and the washer, ensuring correct clamping force.

What is the tensile strength of these bolts?

These E-Series bolts have a yield tensile strength of 190,000 PSI. This rating indicates the amount of stress the bolts can withstand before deforming, ensuring they can handle the necessary clamping loads for your engine.

What does the black oxide finish do?

The black oxide finish provides a durable coating for the bolts and includes a sealer. This helps protect the bolts from corrosion and ensures a good seal against the cylinder head surface.

Product Details

If you're installing Edelbrock Performer RPM aluminum heads on your small-block Chevy, you'll need the right hardware. This Edelbrock E-Series Cylinder Head Bolt Kit is specifically designed to work with those aluminum heads, ensuring a secure and reliable installation. It's important to use the correct bolts and washers when mating aluminum heads to an engine that originally had cast iron heads, as the thickness of the aluminum head and the required washer necessitate longer bolts, which are included here.

These E-Series bolts are well-built with a yield tensile strength of 190,000 PSI, meaning they can handle the loading required for proper head sealing. The threads are rolled after heat-treating for improved strength and form, and the small hex head design gives you extra clearance in tight engine bays, making installation a bit easier. They come with a durable black oxide finish that includes a sealer, and each bolt head is stamped with the distinctive Edelbrock E logo.
