What is the tensile strength of these head bolts?

These Edelbrock E-Series head bolts have a yield tensile strength of 190,000 PSI. This rating indicates their ability to withstand significant force before deforming, ensuring reliable clamping for your cylinder heads.

Do these bolts come with washers?

Yes, this kit includes step-washers specifically designed for use with aftermarket aluminum cylinder heads. These washers help ensure proper fitment and load distribution.

What is the benefit of rolled threads after heat-treating?

Rolling the threads after heat-treating creates a stronger, more uniform thread form compared to cut threads. This process also helps to eliminate stress risers, contributing to the overall durability and strength of the bolt.

Product Details

If you're rebuilding the top end of your Ford 289 or 302 engine, especially when fitting Edelbrock Performer or Performer RPM aluminum cylinder heads, this Edelbrock E-Series head bolt kit is what you'll need. These bolts are specifically designed for Ford small-block V8s with standard 7/16-inch head bolt bosses and include step-washers to work correctly with aftermarket aluminum heads.

What sets these bolts apart is their robust construction. They boast a yield tensile strength of 190,000 PSI, meaning they can handle significant loading reliably. Edelbrock achieves this strength through a process where the bolt threads are rolled after heat-treating, which creates a stronger, more uniform thread form and eliminates stress risers. The small hex head design is a practical touch, offering better socket clearance in tight engine bays. Plus, they come with a durable black oxide finish that includes sealer and are stamped with the distinctive Edelbrock 'E' logo.
