So, How do you fix this?

Valve geometry is not where it needs to be .........
Vale stem tip pattern covers almost the complete stem. Probably "learn to live with it as long as you use stock rockers since they last 200K miles?

forget it-!!!

Only 1 way to change pattern---raise or lower rocker shaft--a strip of shim stock under the shaft is a good way to break pedestal--unless you can cut a tapered strip.

Thanks Lee. Experimeted and looks like I really need to "lower" the shaft in my set-up about 0.020 - 0.025". Lifter preload is set 0.035 - 0.040". I was aware of the required tapered shim for load distribution but breakage? YIKES!
Guess I'll have to live with it. (Or make an "offset shaft" .... )
