Pushrod Rub (Intake side of head)

Moved the rockers up and away from the valves.

As did mine. Which corrects the geometry but then causes this issue in some cases. It really depends on how off your geometry is.

This isn't just a Mopar issue. When I was building my 460, another build documented several different brands in their pivot to cup to roller geometry of the same ratio and compared other ratios and BBC rockers too. Basically it came down to none of them were the same, and to basically test fit to see what worked for your set up. They are different in that they re on a stud and the pivot can be moved some with different push rod lengths, but hat has limitations too. Its all in the geometry.
