I'm surprised that no one has meentioned grinding the rocker arm tip. . .
If roller rockers are accepted next year, this discussion expands arithmetically.

Bingo, you got it...

I had already signed off and went to balancing a crankshaft but I would like to take a second to expound on this. I will never tell you this is correct but I BELIEVE it to be so. If you measure and set the correct rocker ratio, you will always have the smallest swipe pattern across the valve. Yes you can set rocker ratio by measuring the swipe pattern but that length is the result of correct ratio so why not set the correct ratio to start with, but proper ratio can be measured and attained by several methods. Choose your poison
