I have been told that I can expect to have issues between 5 and 6,000 rpm, as the stock goodies weren't intended to rev that high.

I haven't put a hotter cam in any of my stock roller motors yet, but as a general rule if a motor has trouble running up higher rpm numbers it is because it lacks the proper amount of valve spring. The stock lifters are pretty heavy so it may take a higher spring rate to get the valves back on their seats.
