Roller Rocker geometry questions
In the OP's pics we can clearly see from the ink mark(representing the scrub pattern) that the scrub pattern is out toward the exh side of the valve tip.
In The next pic is another head with a similar problem. Note the position of the rocker tip on the valve tip at the closed position.
The next pic shows the same head with the valve open. Note the rocker tip is now even further toward the exh side of the valve tip. As can be seen the rocker tip will not travel back toward the rocker shaft side of the valve tip until it reaches about the 3:00 o'clock position. This would require the valve tips to be lowered about .500" in order to move the scrub pattern in toward the rocker shaft. Looking at the above pic one can see that moving the valve tips up will push the rocker tip back toward the rocker shaft, thus moving the scrub pattern toward the center of the valve.
