I think you need shorter push rods. Get an adjustable push rod and try that.
Pushrod length doesn’t change geometry on shaft mounted rockers OTHER than a slight change in ratio from adjuster position. Once he raises and moves the shafts away from the valves he will need longer pushrods.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
