Nick, I went with the Fast Road Profile Cam from Nigel at SpitBits. It is pretty close to the one recommended in John Davies' article called "Skimming Your Head for a Higher Compression Ratio". That makes a huge difference and puts all that extra compression to work. With the old cam, I could barely make it to redline. With the Fast road cam it pulls all the way past redline and then some...
I also added the oil cooler from Spitbits. If you're going to add it, skip the rubber hoses and go with the Stainless hoses. The rubber ones lasted less than 500 miles before coming apart. Looking back, I wish I would have replaced the valves with the Large Intake Valve 1.44" and Large Exhaust Valve 1.23". RazorBob suggested that I do that and I think he was right.
