Hi all, heres my dillema
Using Crane gold non S/A roller rockers with guide plates.
While mocking it up it appears that for the best rocker arm geometry I need a slightly shorter than stock pushrod. However even with the stock length rod I am nearly bottoming out the rocker on the stud. I only have about 1/2 turn worth of adjustment. With the shorter length pushrod it wont even get tight against the pushrod before the rocker bottoms out on the stud. So I guess I need studs with thinner jam nuts to compensate for the height of the guideplate? This seems like the least expensive solution at this point unless someone can guide me differently.
I noticed in the summit catalog that the screw in studs for oldsmobile/chrysler have very thin jam nuts with the proper size threading above and below. Has anyone used these or can reccomend a stud with a thin jam nut?
Thanks

Might try some lash caps,they would give the same effect as a shorter pushrod,without the stud dilemma.

Thats an excellent idea. I didnt even realize such an item existed. Any problems associated with these?

just make sure they bottom out on your valve stem,and don't put pressure on the retaining clips.I always put some heavy grease on them for assembly,just to keep them from falling off and getting lost.I'll be honest,my current combo uses them,but I'm not all that crazy about them.But sometimes,they are the only solution.I've never had or heard of any problems related to them,but if your careless,I'm sure the could cause trouble.

What heads? How much material was removed to accomodate the screw studs and plates? (I know it may be too late now, but just so others don't suffer the same fate... )
