so the cylinder head arrived today and among the few small differences I worked out my question is the end of the cam nut... the new one in the pic is on the right, my old is on the left.... you can see the difference.... must this be swapped to work in the distributor? thanks in advance guys (so I cant upload a pic for some reason but the end of the nut on my old head has a slot, the new one doesn't)

A picture is worth a thousand words... But it sounds like you have an adapter nut on your old one. New they came with a regular nut. To post pictures you need to host it offsite, such as Imgur or Postimg, then paste that address between

The original cams have a slot cut in them to drive the dist.
The regular nut is 5, the adapter nut is 15.

Yes, you can swap the nuts.

Unless it's a motronic cam there is no reason to swap the nuts. It probably won't even work on an undamaged pre-motronic cam, meaning pre 82 US spec cars.

But what does the nose of the cam look like?
Pics are easy, you need to host them offsite at one of the places I mentioned or many others. Then right click on the picture and copy the address. Then go here and click the Img button, paste, and click img again. But they have to be uploaded somewhere else, you can't just paste them in here. Some sites make it tough to link to the pic, they want you to link to the page with a bunch of other crap on it and which won't work, but linking directly to a pic can usually be done.

turns out the camshaft itself has the slot to drive the distributor. looks like I have to swap the cam from from old head to the new one. I was reading the Haynes manual and this doesn't look like that big of a job....
