Review on Small Block Chevy Stage 8 (8911B) 1-1/4" Header Bolt Kit by Anthony Grover

Revainrating 5 out of 5

I bought a set of Dougs manifolds and used a Remflex gasket

When using non-original manifolds, the screws must be 1 1/4 be to fit properly. With the Stage 8 header mounting bolts, you don't have to worry about them being reversed. Run the engine for 15 minutes, then retighten and secure the bolts.

Pros
  • The double hex head includes a countersunk 3/16" hex head for easy installation
Cons
  • Crumpled packaging
