Arnie,
This sounds bad as pushrod failure usually does not happen unless there is
contact with the valve to piston or some other physical contact or bind. If
this contact did happen and you replace the pushrods it will likely miss due
to the new tweak that you have in the valves affected. If not you were very
lucky.
Couple of questions: Any spirited driving like some high RPM? Is it possible
that the Rocker bound on the rocker stud? Is it possible that the springs
coil bound? Is the cam solid or mechanical? What is the clearance between
the spring coils at max lift? Were they both Intake valves? Are there valve
reliefs milled into the pistons? Did you check valve to piston clearance? Do
you have guideplates and if so do they show any wear?
Best Regards,
