Modern cutters in for the head machines can cut multi angel jobs in just one pass. Just a matter of having the right tool.

A valve grind job is cutting the valve and valve seat to match. You will often hear terms like 3 angle and 5 angle valve jobs. These tend to cost more due to the increased labor (you are cutting each part 3 times or 5 times, as opposed to 1) and gives you the benefit of better flow characteristics through the valve opening.

can someone explain what a valve grind job is? What does it accomplish? how much does it cost to get done? thanks
