Some 5.9 roller cam help from y'all please

Engine is a 9:1 factory bottom end 1996 5.9 magnum.
EQ heads with 192/16? valves and Hughes 1110 springs.
LA Edelbrock dual plane Performer
Edelbrock 1406 (600) cfm with electric fuel pump.
1 5/8 tube headers and dual 2.5 inch exhaust through Flowmaster 40's.
Stock converter stall.

This car will remain a freeway car and have tall gears.
It will run 99% in the idle to 5000rpm range, so torque is the goal here and not top end.
Do not want to go the regrind route unless I have to
I need a good roller cam upgrade for it, and a little lope is fine and it needs to stay below a .500 lift.

So much information out there, but almost all of it is for top end, and I'm thinking I need to stay more in the towing range of cams for what I want.

Thanks all.
