I don't think cams are considered a bolt on. You are adding something internal, not just bolting something to your existing motor. The procedure is in the fsm to install camshafts.

the cams are not a big ordeal. once the cash is there after they are available, it will be done.
bolt ons are usually external mods that are bolted up or to the engine. (IE: intake, headers/exhaust, pullies, even a simple NOS system and ECU) i have seen cams in some circles classified as bolt ons, and some as bolt ins. call it a strap on for all i care as long as i get more power!
