Do you know if the longer push rods will effect the wipe pattern on the YT's?

The push-rods length shouldn't effect the wipe pattern only the preload, shims are used to set the wipe pattern with the YT non-adjustable rockers.

FYI, if you change/re-adjust the wipe pattern with different shim heights it will change your pre-load.

That's what I was wondering if the two were independent or not to each other.

With the Yella Terra's, start with cylinder #1 and install the rocker pair at TDC. Rotate the crank 90 degrees and do the second cylinder in firing order. Continue until all the rocker pairs are installed.
