Review on Dual End Suction Valve Grinding Lapping by Damian Grotting
Waste of Money: Poor Performance
Through trial and error, I found that these valves were a complete waste of money. They did not grind and lap with the precision and accuracy required for Automotive engine tools. The material was flimsy and barely held up for one time use..
Pros
- None
Cons
- Poor performance and quality.
