MORE VALVE TRAIN QUESTIONS................

The non-adj rockers will be fine with whatever prods you have that position the prod cup within the range of the lifter travel. The XE 262 is going to be rpm limited so the springs should be ok.

Same deal with the adj rockers. Adjust the rocker so that prod cup is depressed about 0.020", not critical.
You will now get arguments about how many threads of the adjuster are showing & how it affects lift, but with this mild cam I doubt you could measure any difference on a dyno.
