  • Non-Automatic

Excellent gaskets for engines and engine parts

They fit great, studs are great and the quality of the machine is great. However, be careful when installing the gasket as some types of valve covers can try to slip out.

Pros
  • Billet 3/4" valve cover gasket
Cons
  • Upgrade available

Pros
  • These require a gasket and/or sealant on both sides of the spacer

Save a Life!: Engines and Engine Parts

Just what I needed to clean the rocker arm. The only thing that would make it 5 stars would be if it came with valve cover bolts, but to be honest it was stated that it didn't come with hardware.

Pros
  • Includes: 2 Spacers and Mounting Hardware
Cons
  • Expensive
