Yes, you can, and yes, they're better...
Having said that --- I would not suggest running a new set of them if you're still running a higher mileage stock cam. These springs are 100-110 seat pressure, and would be a little too stiff for a worn out stock cam. They'd cause it to die a quicker death.
If you install a new cam, then these will work great!
If you're simply replacing the springs and nothing else, I'd recommend a little less ridgid spring, ie, use the OE style. A new set of those will wake-up the car considerably if your current springs are 60k+ miles.
