yeah, i used the crane directions when i was in youre boat.
you probably won't want to do this, but pull off you're lower plenum, and MAKE SURE youre getting at least 20thousands pre-load on the lifter. lol, when i did heads on my car, i found out that the rocker arms were bottoming out on the pedistule before i got the correct preload on the lifter.
and i thought that you only need to shim you're rockers if you have too long of a pushrod...
but yeah, give that a try.

OK, my first post I was just replying towards your (86blue) first post, my second post I was just replying to carbed87's post. Now I am replying to your post again. Does that clear things up?
There is adjustability with pedestal mount rocker arms. It is a combination of pushrod length and shims.
