Call Comp Cams and ask to speak to a tech. They are very helpfull and knowledgeable. Tell them engine size, trans, converter, and what you are going to use the truck for (towing or cruizing,etc.) Just google them for their number.

BALONEY!!!
Call Comp 4 times, you'll get 4 different techs and 4 different answers. About half of those guys couldn't swap a cam if their lives depended on it.

Vortec heads will require an intake swap but will make a good bit more power.
If it's a daily driver, don't go too big on the cam. Fender shakers are impressive to listen to, but a royal pain to drive. I'd stick with something small, 224/230 is about as big as I'd consider if you need vacuum for brakes, etc.

Regarding the cam: First determine what you want the engine to do and at what RPM.
Then pick your cam grind based on that. You'll want to include your differential ratio and tire height in your equations.
