Rocker Arm help

Pishta,
Let me preface this before I specifically answer your question [ post # 76 ]. All of my posts in this thread are in reply to the original post, #1, where the OP refers to the 'terrible geometry', where he specifically refers to the roller tip coming too close to the valve tip, exh side, at max lift. A rocker has two parts, prod side & valve side, & both affect geometry, max lift. Since this rocker is too long to start with, fixing the problem that concerns the OP, no matter what the 'fix', will almost certainly result in reduced lift, bad prod angle, or something else that is less than optimal.

The picture in post #1 are not great, but you can see enough to see the problem.
The rocker needs to go down, not up. With the valve on the seat, you have to look at the line from the roller contact point [ NOT the roller pivot, a common mistake made by many ] to the centre of the rocker pivot mechanism; in this case, the shaft centre. Now imagine a line up the centre of the valve stem. You can see that where these two lines intersect, the angle is less than 90*. If the rocker is lifted, it moves the roller tip contact even further towards the exh side, the opposite direction it actually needs to go. If this was done, the roller tip comes close to running off the edge of the valve at full lift.
If by some means [ correction kit? ] the rocker is raised AND moved towards the intake side, the above mentioned angle becomes greater, maybe over 90*. This might centre the roller better on the valve tip, but then causes another problem: loss of lift & a severe angle of the rocker at max lift. The prod side of the rocker is also affected & may result in severe prod angle at max lift.
