Knowing what I know now I would have stopped at the cam upgrade.
As for the bolt cutters I would advise against them but that is just me.

I'll leave the bolt cutting talent to him,as for my ideas I wasn't thinking all out,port & polish , shaving and all that, just new everything and a nice cam that I'll notice. We'll see how the compression is, I have a tester.

At the time your bike was built, like every Harley since long before, it had to meet EPA regulations on noise and exhaust emissions. Most of the tuning you will read about for our Evos is simply undoing some of the harm done to performance by those regulations. They affect the design of the air filter housing (actually a muffler), carb settings, cam profiles, also (and often over-looked) ignition timing and advance curves.
You probably by now have a good handle on answering your original question, but as you finalise your project, consider replacing the ignition module as well. Each of the various things mentioned above will contribute to making your bike so much better to ride and enjoy.

The86 has the "good" cam bearing in it already. No need to change it unless you really want to. It's a matter of how much other stuff you want to do. Just put the cam in? You should put new lifters as well, as those are due now at 40. Re-use the old pushrods or put new adjustables in? With adjustables, you don't have to pull the rocker box tops off, so you don't have to pull the tank off, so you don't have to pull the seat.... But if the rocker boxes are leaking, then I'd certainly go in there and fix that and re-use the fixed ones.
