The geometry in post #1 is very poor for whatever reason, valve length, rocker dimensions wrong.
To use those components and get a centered roller-on-the tip, the rocker body needs to sit lower. Another 'fix' might be lash caps.
Just “because” I may could possibly miss something, I went back and looked at the original picture.
If you do you say and low the shaft, it WILL get closer to the rocker. Then the rocks will hit the spring. Then you will go right to the old “use a beehive spring” theme you love.
And a lash cap, the standard Harlan Sharp answer to all things geometry will make it worse.
That shaft has to go UP and AWAY from the valve for it to be correct. There is no there acceptable correction.
It’s no wonder so many Chrysler engines are out there with crap geometry.
Mike at B3 racing engines has taken the time to write 4 very informative articles on shaft rocker geometry and has them posted on his site.
It’s a must read for anyone wanting to understand geometry and how to correct it.
