Mike:
I'm guessing you are using hydraulic lifters. I now understand why you chose the cam you did from Ultradyne. I went to their web site tonight, their reccomendations seam very conservative. I would reccomend Crane grind number H-296-2. It is number 6 on the link below. It has a 112 degree lobe seperation, which will give you a nice idle, 234 / 238 duration @ .050 and .554 / .563 lift.
