I have a 74" shovel out of a '77. It has aluminum pushrods and a solid lifter cam. How do I properly set the lash? I know how to do it with hydraulic lifters, but not the solids. I'm paranoid I'll set them too tight, because I have seen shovel valves whack each other. Any tips would be appreciated. Thanks.

First of all the engine must be cold
Remove the clips and xpose the push rods and hold the tubes up with a clothsepin or wire'bla bla bla.
pull the plugs to make it easier to turn the engine over
on each push rod do the following rotate engine until valve is completely closed (tappet at lowest point) pushrod will be at its slackest point.
loosen jamb nut
adjust pushrod so there is no up and down movement at all, but the rod still turns freely with thumb and index finger. tighten the jamb nut and check to see if there is NO up and down
you may have to repeat if there is.
Repeat on all rods and you are done my friend.
