Even the crank indexed to the keyway can be out.
Just slam the production stuff together but if you find yourself asking if it should be checked. Then it should be checked.

That's why you check TDC to the damper mark, and you can time the engine correctly after correcting the alignment of the timing tab O mark.

Once you figure out what you need, just get the bushings. They come with 0,2,4,6,and 8 I think. Drill out the hole that the cam dowel goes in. Put teh bushing in that you need , make sure you line it up right. It takes a little thought, did for me, first time I've done this, and make sure you put the offset the correct way and recheck it. I have a roller cam so I have the plate and roller button set up from Mancini, so I drilled the hole all the way through, but if you have a solid cam, just drill the hole far enough so the bushing fits in and can't come out the other side.
Go to the comp cams site, it explains it pretty well on how to degree it in. That is what I used. Hope that helps.

What Dodgeguy101 said. Drill the pin hole out (not all the way) to .406" (13/32). Find exact TDC then degree it & see what bushing you need/install it/degree it again to check it/stake it & to elim some confusion although you are degreeing the cam which turns half speed of the crank these degrees are CRANK degrees as you are measuring off of the degree wheel/pointer on the CRANK.

Security against what?
I do it for the simply reason that it's easy to break a pin if you load the end. If you try to shear it, hard to break.
Since the cam sproket is thick than the bushing. If you drill all the way through. The bushing will not rotate but it is free to walk forward against the cam bolt washer. When if floats to the rear, that's a good thing. It places the camshaft dowel in a shear load. Strong. When if floats to the front. You are now driving the camshaft with the tip of the dowel.
So drill the hole only deep enough to keep the bushing near the back of the sproket. I'm sure this has been overlooked a million times but shear load is why I only drill part way through.
