Product Details

The Speedmaster PCE279.1004 head stud kit is engineered for Chevy Big Block 454 engines requiring superior clamping force and reliability. These premium head studs provide a significant upgrade over factory head bolts, offering improved head gasket sealing and resistance to head lifting under high cylinder pressures.

Construction and Materials:

  • Manufactured from aircraft-quality 8740 chromoly steel for exceptional strength
  • Cold-forged construction ensures molecular integrity and dimensional consistency
  • Heat-treated prior to thread rolling and precision machining
  • Rated at 190,000 psi tensile strength for extreme durability

Complete Kit Includes:

  • 12-point head studs for positive engagement and reduced stripping risk
  • 12-point nuts for secure fastening
  • Hardened parallel washers for even load distribution
  • Washers ensure accurate torque readings and prevent nut galling

Head studs offer advantages over traditional head bolts by eliminating the twisting motion during installation, which can cause uneven clamping loads. The stud design allows the fastener to stretch uniformly along its length, providing more consistent and reliable cylinder head clamping force. This makes them ideal for performance applications, forced induction setups, and high-compression builds where maintaining head gasket integrity is critical.

TIRE SHIPPED OUT PRETTY QUICK

Thx

Only issue was lack of shipping confirmation, no order update and the unit showed up at my house in a full size 18 wheeler :)

Placed order, recieved order. Thats how it works.

During a regular boating season I usually damage one aluminum prop per year . Once again, I needed to replace my prop on a 50hp outboard that I use during fishing and deer hunting on the Missouri River. In past years I have had to allow time for the new prop to arrive. Not this time! The people at Boatplicity got the prop to me the very next day! And I paid the lowest price I have ever paid for the prop. I now have Boatplicity on my favorites list and will definitely use them for all my boating needs.

GOOD PRICING AND I APPRECIATE FREE SHIPPING

Good price and simple transaction. Fast shipping and good communication.

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.
