OP,
We're getting into the mix a little late here but wanted to chime in. You've received some great advice from the community. We'd like to add more on the wanting a "choppy idle" subject. More often than not we get customers with stock combos wanting that old school, racecar, thumping idle. If it isn't rattling windows and setting off car alarms it isn't choppy enough!
Then we sell them said "chopzilla" cam for their mostly stock combo. On down the road, they get the engine running... Well sort of. This is when the customer calls us and says the following. It's hard getting this to idle, it smells like raw fuel, and the driveability isn't that great! If that sounds like what you're after for your stockish 6.0 get something like our Pro LS stage 4 SUM-8709R1. Specs on it are .625/.605, 238/246, 113+3 with 16* of overlap. With a 9* IVO and 16* of overlap it will have a heavy lopey idle. The thing is to make a cam like this streetable you need to be willing to work on quite a few other things. Things like raising the compression, stall converter, gears, intake, exhaust, fuel system, custom tuning, etc.
Example of the 8709R1 idle in a 6.0.
What we would do before deciding on a cam is do like others have suggested. Find out what the engine currently has in it for a camshaft. That may take degreeing it in as 68Formula suggested. Ride in someone else's car/truck with a healthy camshaft in it. See what it's like and ask them questions of what all they had to do to help make it street-friendly. Then come back to the thread with these findings and let the community know. Maybe you'll end up with a "stage 4" cam. You might end up with something like our stage 2 SUM-8707R1 or stage 3 SUM-8708R1. The stage 2 would have what we consider a steady lope with its 3* IVO. The stage 3 has what we consider an aggressive lope with its 6* IVO.
