cam for 340 street car

Engine has X-Heads with 2.02"/1.60" valves. I´ll do no porting, just smoothing out casting burrs and sharp edges.
Car is driven mainly in town at 40mph in D. But as it´s not a daily driver, it should make some serious stoplight performance (0-50mph) and should perform well when leaving town or accessing autobahn (40-100mph).
Now it makes no sense to shift above 5000rpm, but I´d like to extend the manual shift points to almost 6000rpm, so (with the 727 delay) the engine never revs more than 6500.
So I want to help mid range and top end without sacrificing the low.
I want to use a hydraulic cam and stock stamped rockers.
Combo should stay like this for at least 3 years/ 10k mls.

Thanks
