redline, amsoil, mobil 1, etc.. all have good heat tolerance. 300°F is scary but the oil will survive it. SS guys see super hot oil all the time and live with it becasue they have to.

don't do the oil/water exchanger unless you believe that you have sufficient extra heat capacity in the water cooling system - last thing you want to do is overwork the radiator in an effort to reduce oil temps and end up overheating both systems. try adding a bigger or second oil/air exchanger first or adding additional oil to the system - mass helps. big pan, oil resevoir, huge external filter, etc...
