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.
