Another Pushrod/Preload Question
It depends if you buy pushrods that are specified in gauge length (like Comp Cams) or by total length flat-to-flat (like Manton).
If you use pushrods specified by the gauge length, then you would need 7.3125 + 0.050 = 7.3625 since you used the Comp Cams length checking tool, which gives you a gauge length measurement.
If you use pushrods specified by the flat-to-flat lenght, then you would need pushrods that were 7.3775 from flat-to-flat as you showed above.

4. Ball/Ball designs are to be ordered by overall length
measurement. (The standard flat diameter on the ends of the
pushrods is 0.100")

Curious if you spoke with Terry. When I called he returned my call from his car and was very helpful (while driving). He made me one pushrod with a removable end so I could alter the length while I was setting up the motor.

I only saw one mention of Shane @ TRs method in this thread. I have used it a bunch of times and have come up with silent valve-trains each time. I guess that's the method OP started out using at first.

Verdad Gallardo Yes I started with Shane's method first, then went ahead and used an adjustable pushrod to get measurement with that also.
