Product Details

If you're working on a 1961-1979 Pontiac 326 through 455 cubic inch engine and using Edelbrock's Performer D-Port cylinder heads, this head bolt kit, part number 8561, is what you'll need. It's a complete set of head bolts and hardened washers designed specifically to work with those heads, ensuring a solid seal for your engine's top end.

These bolts are made from high-strength steel, rated at 170,000 p.s.i., and are cold-formed for molecular integrity. They're also heat-treated before the threads are rolled and machined, which helps maintain their strength. A practical detail is the reduced diameter bolt heads; this design means you won't have to remove your valve train when it's time to re-torque the cylinder heads, making that maintenance step much simpler.
