Before installing, Russ looks through each push rod to make sure they aren't blocked. Every now and then you get a little grease or a metal chip in one he says, 1-2 times a year, but enough to destroy a pushrod if you don't catch it.
Once they are all cleared he rolls them on a flat surface just to make sure they are all strait. They always are he says, but it only takes a moment to check.
They go in with yet a different assembly lube. If you're keeping score, he has used 6 on this motor so far.
Drop them all in place.
LOTS of lube.
AAAAND yet a different lube on the top of the valves.
Back to the peanut butter, because no studs.
Set the first couple of rockers in
Then tighten them down
He twists the pushrod as he tightens the bolt down. He wants to feel the pushrod start to engage 1/4 to 3/4 of a turn away from the lifter bolt tightening up, to set preload on the lifter.
Halfway there.
Russ says with the way the head is built the 3 and 4 pushrods get really close to the head, so he wants to inspect and make sure they aren't rubbing. If they are we'd have to clearance the head or go down to a 5/16 pushrod.
They are close, but they don't touch. This is as close as they get.
And then he does the rest (I didn't snap a photo)
