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.
