I don't know about yours, but my 96B6 came stock with 98's in 1 & 4 and 100's in 2 & 3. So just make them all the same #100. I don't have Dale's stage one kit, so maybe you may want to give him a call!!
Is that what he sent you is 95's ?? Dale knows more then me. I'm at sea level and 95's would be way to lean for me IMHO.
Put something over the drill bit, like the plastic part of a disassembled ball point pen,
or a piece of rubber hose so only the tip of the bit will break through. And you don't have to replug them, leave them open so you can do fine tuning.
You want to keep the floats at stock hieghts, but do check them to see that they are correct.
