- Start date
are these pedastal or adjustable? if they are pedastal there is no adjustment just torque em down to 18-20 ft/lbs. if they are adjustable then follow the instructions in this link
doh i couldn't open the link some trouble with adobe. anyways go to comp cams go to instructions. scroll down to magnum rocker install and follow the instructions for hydraulic lifters.

So i should go to the crane site check the procedure and get the correct shim pack? If i remember right the guy that builtthe car said they kept backing off so he used diffrent bolt's or something to that degree? Is this process a pain in the ass or does it just sond confussing? Oh BTW what is there address for crane? I'm internet stupid!

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.

Yeah, you need shims when you can't reach the desired 18-20 lb-ft within 1 turnof zero lash.
I was just kinda responding to what the guy above me had said.

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.
