Boost your vehicle's performance with these valve upgrades

These valve upgrades have greatly improved the performance of my Automotive vehicle. I noticed A significant increase in power and acceleration. The installation process was also relatively easy. The only downside is the price, they are quite expensive but worth the investment for any Automotive enthusiast looking to enhance their vehicle's performance. .

Pros
  • Improved engine performance due to increased valve diameter
Cons
  • Possible need for additional engine modifications to optimize valve size

Pretty simple description, hard to go wrong

I used these to fix some minor valvetrain alignment problems on my roller rocker arms remedy. Didn't completely solve the problem but helped fix it in the standards. also helps create more contact area at the tip of the valve stem for the rocker arm to make contact with.

Pros
  • Packaging dimensions: .762H x 14.986L x 9.906W (inches)
Cons
  • Could have gone for a newer model
