No, running even to 7800 wont do any harm plus I doubt they would ever advertise them as NSR 7500 rpm and then let the people blow theirs engines.I have a cobra jet and plan to run 7900rpm. Even running to 7500 would be too much and that came from tech guy at Comp cams.
Like I said - spoke with Comp Cams as well and they said those are NSR up to 7500 rpm.
A shop guy would tell you everything as long it makes money for him - luckily I have my own brain...
