Custom pushrods, how much stock lifter preload?

Although mine is a 440 .525 lift cam it happened today. Hopefully it was just a weak rocker.

That stinks, I would try running hollow pushrods if your lifters have provisions to feed oil to them, that would get more oil at the pushrod-rocker mating point at least.
