Installing rocker arms

[townethug]

I searched and didnt really see anything that helps me. I was reading the hayes manual about installing the rocker arms and it says to rotate the cranksaft until the push rod is on the base of the camsaft (I am guessing this is the lowest point). How do I know when its on the base of the camshaft? What methods do you use or would you suggest?

Thanks

I dont know, this is the first time i have done anything even closely related to this stuff. These are stock heads and stock rocker arms. Please explain the difference.

They are probably pedestal then, The easiest way to explain it is that the pedestal has the threaded bolt that you screw into the head, the Studs have the threaded bolt protruding from the head.

I think both of the above links are for Stud mount rockers. Here is one for pedestal mount

A manual will often tell you which rocker arms you can adjust at #1 TDC compression and again #1 TDC exhaust. On your stock 5.0 heads you should have pedestal rockers which will only need to be torqued down unless you have made some changes. If you have then you will either need shims, different length pushrods or adjustable rockers. When you set them half of them can be adjusted at one position and half again after rotating the crank. If you are tightening them and they suddenly get harder to turn before you get them tight you are probably not at the right crank position and what you are feeling is the resistance of the valve spring as you are slowly opening the valve.
