Engine Quest pushrod question

Thanks for all the advice. I've done all that pushrod checking before. I have the shortest checker tool but it's not quite long enough so that's why I used my stock pushrod as a checker. It's also hard to do when the lifter isn't pumped up too. Lol. It just bugs me when it's recommended to use certain parts and they are incorrect.

After speaking with that Jesse fellow in Ontario who has built many very similar motors and what 71beater and others have mentioned, I'm confident in my decision.
