Valve Geometry

[owdlvr]

As I understand it, perfect valve train geometry is going to end up being a compromise between the wipe area on the lash cap and the angle of the pushrod to adjuster. Here is where I've got it set currently, with no shims. The pushrod is an adjustable rod set to loose-zero.

Zero Lift:



Half Lift:



Full Lift:




wipe area, which I think is pretty spot on?

If I understand this correctly, for the pushrod side of things at half-lift, I would ideally want to add a spacer under the rocker shaft mounts, which should straighten the slight angle out that i can see in the photos. But doing so will move my wipe area up on the valve, and I'm pretty much centered right now. I *think* the valve side is the more important of the two, considering how close I am, so I should just stick with what I've got here. Correct?
