Dr. Evil,
I would recommend that you go with 10.5 to 1 forged pistons and use compression releases so your not hard on the starter. You do not need a high speed starter just a harley battery and harley standard starter it spins faster than the after market ones. This was proved to me by the guys from S&S with my 124 motor. The stock starter / harley battery turned it over faster than a high torque starter will so dont buy into the Torque deal its a lot slower and doesnt allow the bike to fire as well.
I would have my stock harley heads worked on its not worth buying the HTCC heads or the cnc ported heads as you will not see the gain you would expect for the cost and they can differ greatly in the quality control as well as they have a high spring tension. Also helps you keep the sleeper look. (Some head guys like to put their name on the outside personally I do not want this if they want to grind their name on the inside great but leave the exterior of my heads alone)
I would use the 251 cam personally over the 203,204, or 211. I do not like the 211 cam as it comes on at about 3500 was sluggish for me till there and ran out quickly at about 5300 rpm. The 251 pulled steadily for me all the way to 5300 from about 2000.
The 204 was a great torque cam, but has nothing really in top end it dies significantly after about 4800 rpm.
If you are going Gear Drive the Andrews 55g cam or the S&S 570 cam are both good choices.
Personally, if your looking for performance I would not use the VH pipes, I would suggest looking at a 2 into 1 like Thunder Header, D&D Fat Cat, White Bros E Series pipe. If you don't like the 2 into 1 look then you could also look at the thunder header with the heat shields and fake 2nd pipe to continue on with a true dual look.
Power Commander over Race Tuner if this is a EFI bike.
I would also look into using a S&S Reed Valve for oil flow. They will already be taking out the cams anyhow its not much more to put this behind the oil pump at that point.
If you stay with a Harley Cam you will want the perfect fit pushrods vs adjustable ones.
I would recommend new lifters since your doing all this (Jim's or S&S or Zippers)
For headwork you can use
Cycle Rama (Wes), Small Block Charlie (Charlie), Street to Strip (Cliff), STD, Redman Racing (Allan).
you may also consider if its an EFI to bore out your throttle body a bit to allow for more air / fuel flow the stock one is a bit limiting and you can get it done for about $325 dollars plus shipping.
I would also recommend a Rivera Pro Clutch.
