Review on πŸ”’ Stage 8 8913 3/4'' Locking Header Bolt Kit for Ford Small Block - Enhanced Fastening System for Optimal Performance by Jeffrey Mosqueda

Revainrating 5 out of 5

Ditch those standard bolts and get these

A very good kit that keeps the bolts from falling out. I highly recommend running the motor a few times and tightening as needed BEFORE installing the clamps. I had to take them apart 3 times because the gasket I used shrunk with thermal expansion. I used folded metal spacers. Now that everything is done, they do their job as intended.

Pros
  • Weight
Cons
  • Lots of stuff
