So I'm getting an adjustable cam gear, but reading through various articles on various sites, it seems even degreeing a cam can be complicated due to asymmetrical design of the lobe and then there seems to be multiple ways to do it. Anyone have any advice on which tool would be best suited for our cars and possibly some instructional insight as to going about this process? It's a tool I probably won't use too often, but I'd like to have it around for future use.
