George, he knows which heads I have, as well as the fact that he supplied the stands, etc. Given that, he provides the push rods at proper length I guess....I'm guessing there, but I believe that's how he knows which ones to supply.
As for the ends, one definately fits in the lifter cup, and the other being smaller fits into the rocker cup. Instructions?
I know none of the pushrods are hitting the manifold holes and everything seems to be pretty well lined up.
