Valve Geometry

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?

Thumbs up geometry.

i would say your're there really, and as good as you need to be . i like the adjuster screw with just a couple of threads showing underneath the rocker for maximum strengh, sometimes grinding the underside helps clear the adjuster foot, and looses a bit of weight also. good luck with it.
