how would you adjust the cam to the crank/piston? In my opinion I wouldn't recomend sloting out the cam pin hole on the cam sprocket.

from what i had understood from other sites, degreeing the cam involves making sure that TDC is aligned perfectly with the centerline of the cam, not modifying the cam sprocket.

You're right! But lets say the cam is off, which most likely it is then really how would you go about adjusting it? Basically by slotting out the cam sprocket pin hole so that way you can move the cam. Then take in to account cam chain wear after you get it correctly set.. There goes all the time you spent degreeing your cam.

Slotting the cam sprockets is the correct way if you are degreeing cams, this is assuming it uses a typical nut/bolt arrangement, and isnt riveted.

With that said, theres no point in doing it on a SOHC engine (intake and exhaust points are fixed relative to each other), even if youve shaved a bit off the head or jug. Even at .025 its just not gonna throw the cam off enough to make a notable difference on the dyno.

Cam degreeing on DOHC engines can be quite useful, since you can independently adjust each cam, and control overlap, etc etc.

It takes a little practice to do cam degreeing, it really helps if you have some one to physically show you how. Theres some simple math to do as well. Its more involved than you might think.

I have this kit here:

Dale also makes a video tutorial for n00bs:

Hope that helps.
