I fear they may be bottoming. It's close for sure.
For the cost of a set of pushrods, I'd rather go that way.
close to bottoming out would be WAYYY too long then, if you're looking at custom pushrods. they should be "just barely pushing down" on the plunger inside the lifter...remember "zero lash plus 1/2-3/4 turn on the rocker"
make sure that you're checking them with valves closed on the base circle, I forget the sequence, but it's something crazy like TDC #1 compression stroke, check intake on #1 and exhaust on #7, rotate crank 90 degrees, check intake on #3 and exhaust on #4, rotate crank 90 degrees.
if you want, I can look it up in my rebuild book and post the correct sequence if you need?
