Re: Test lifter for push rod length check?
For flat tappet hydraulic cams, I have two test lifters that have their guts removed, and a solid spacer inserted to keep the button down about .030 in the lifter. I also have done the same for hydraulic roller cams. I always do the push rod lengths with the engine on the build stand, and no intake manifold in place, E-O, I-C method and a rocker arm tool as well.
I am big on making my own tools, and have the machines to make them, but modifying a pair of lifters to set the button correctly isn't that hard to do.
