I looked through the tech archives and didn't find anything. Does anyone have a PDF file on installing cams on an ironhead? Or can someone walk me through it step by step? The motor is a 79. Thanks for the help.

Think this has been covered before in a few threads here....
Kinda a bit hard for the search if you don't have it worded just so-so..

I'll see if I can help...

First off...
I would load the cams into the cover to see how well each fitment of the gears are...No need to worry about the timing marks for this test.

Just sit them in and feel for backlash....On each gear mesh. There are four that you will be checking...Five if you also check the pinion gear to # two cam and six if you check # four cam to gen. idle gear...
If the cover bushings have alot of wear on them...The backlash will be noticed being alot....
Any more then .002 would need to be address...Or your going to be hearing alot of noise from the cam chest when running.

Once that has been accomplish and given a GoAhead..
Can load one at a time in the case and with the lifter block being pulled (Out of the Case) and check for end play...Only need a few bolts holding the cover on for doing this.

The timing is pretty easy, just make sure all the dots or little lines all line up. They have multiple marks, so make sure every mark has a corrosponding one on the other cam. The number 2 cam has 3 marks on it, one for the pinion, one for cam 1, and one for cam 3. Number 3 cam will have 2 marks on it, one for #2 cam and one for #4 cam. The cam numbering starts at the left, or the rear exhaust cam. Also install the spacers with the 2 holes in them so the bevel in the holes faces out toward the cams.

I'm PRETTY sure the factory manual covers cam alignment.
