I don't see "crap" pushrods. I see three different types. Probably all the correct length, but if that was my engine and as cheap as pushrods are, it would get a new matching set.
Yup. Somebody somewhere in the past bent a couple or motor has been apart before and a couple were lost or whatever.
Look all to be same length but..... I think I'd get a matched set.
( and yes. I am a cheap s.o.b. so....)
