Rocker geometry

Since a few days I work on the correct rocker geometry. The adjuster screw should be exactly in line with the valve stem at half lift. An adjustable push rod is required to do the job right.
As there are so many modifications compared to a standard motor, this is a difficult task, But I will get there in the end...

Currently, still not perfect @ half lift, even though I already shimmed the rocker shaft by 2 mm, I think I will have to modify the rockers like here (pic found on thesamba.com):
This modification will finally allow the exact geometry (hopefully...)
Afterwards I can shorten the CroMo push rods to the exact length.
