Rick, when I switched to a different head and valve angle I had a very wide swipe near the center. I had to increase pushrod length to get my geometry correct and in doing so moved the swipe toward the exhaust side of the head. As I increased the pushrod length my swipe pattern decreased. Remember a large swipe indicates the roller is sliding across the valve tip and not moving in an arc that transfers the cam lobe lift directly to the valve movement. This also is where it loads the valve guides on the rocker axis.
It's more important to get the small swipe first while watching where it is located on the valve tip. You can run the swipe toward the outer 1/3 of the valve tip whether is toward the intake or the exhaust to get the geometry correct just keep away from the edge. I'm .050 from the exhaust side edge of the valve tip and my swipe is nice and narrow. All looks good and runs great. Also if you are increasing the pushrod lengths watch the rocker on the stud shank. You don't want it riding up too high and be on the threads. A longer stud or shank area would then be needed.
