Shimming old lifter to simulate preload for valvetrain setup
That's all we're checking pushrod length for. Just for the sake of checking.
Because I don't want to not check it and find out to late, 3,000 miles down the road, that we have been running .010 from the top or bottom of the travel after its to late.
I'm pretty sure the stock pushrod will work for what we're doing. But since I have the tools to check it. I'm checking it.
