i like to soak the lifters in 20w oil overnite,i don,t soak the lifters, oops,i ment to say rocker arms i oil the trunion bearings and the roller bearing.i use assembly lube on the pushrod cups and the valve tip.i also spray a valve trane assembly lube all over the springs,rocker arms,and pushrod,s.it is made by comp cams.imo,the springs really need lube until the oil covers them after initial startup.

Oven works well for getting oil in hard to get places also. I have an tendency to over clean parts if I have any concerns what so ever. If I have to reclean pistons and rods after assm I just set in the oven for 10-15 min at at 200 plus degrees. Engine assm lube works its way in btwn the pistons and pins very well. Roller Rockers I've used just a heat gun.

Crude Intentions

An earlier post has me thinking. Someone was mentioned from trunion to roller is different on different rockers. Would that be same ratio and different manufacturers or just different ratios? Maybe some of us can measure what we have for i formative purposes. Use a mic and go center on center. Unless someone already has this info.

You can purchase them longer/shorter. Does seem messed up from one manufacturer to the other that some will differ.

They do vary quite a bit from brand to brand, architecture wise.

They should make an adjustable roller rocker with precision measuring capabilities like adjustable pushrods. I'd bet most rockers are purchased during build and probably overlooked my many.

For a while, crane offered their "gold" rockers, with "TR" fulcrums, that were larger and stronger, then for the last couple years, made it standard on their gold series before they switched vendors or whatever. I had a crane gold rocker, crack exactly like this one did. The crane was made in 1985, was found cracked in 2010, with tons of hours on them, god knows how many. The scorpion in this picture, had less than 100 hours if I recall. It was on a hyd roller setup.
