push rod ?

so i searched push rod lengths and the writeup and video on using adjustable push rod to check for proper length. well i dont have and could not get my hands on a adjustable push rod over the weekend. so i figured i would follow the process with my current push rods but i had four on each side did not sit perfect in the cups of the rocker. I took one of them that did and went to napa and matched it up to get the correct size/length for my test

i figured doing the test with my current parts would tell me if it was done right and i was good or needed to get an adjustable rod and start from scratch. i cleaned and marked the top of each valve attached and tightened down the valve train and rolled the motor over and watched the valves open and close 5 times.

i pulled the valve train off and bingo the wear mark was right across the center so they must have milled the heads/block and i think i should be good.

thanks for all the help
