The contact pattern on the tip of the valve should be centered and as narrow as possible. Adjust the pushrod length checker until you achieve the optimum contact pattern, measure the length of the checker and order the appropriate pushrod length.

The contact pattern is rarely centered but getting it as narrow as you can is good.
