Cam & head upgrade 360 mag

Truck weighs about 5000 pounds, give or take a couple hundred pounds.
I'm guessing the converter has the stock stall, whatever that may be.
I did have the transmission re-built and it got a new converter, idk what the stall is on it but I do know it's a non lock up converter and it does have the transgo Jr shift kit in it.
Right now I normally shift at 4500-4800 rpm whenever I'm running it against someone in the mud or on the street.
I realize that cam does have quite a bit of duration, but if I do decide to get the camshaft I'm also going to get the new heads and I will run a thinner head gasket, a .028 thickness head gasket which will bring the compression up from 9.0:1 to 9.5:1.
What camshaft would you recommend for this truck?
