440 vrs RPM’S

Whats your opinion?
I have a well built 440, good Eagle bottom end, buillet timing gears, sold lifter cam, Harland and Sharp roller rockers, reworked Eddy heads, you know good stuff. Every thing is set up for a power band of 4500rpms to 8500rpms.
This motor pulls strong in the upper rpm range, but I'm old school and have all my rev protection set at 6800 rpms. The engine at that point still is pulling and reving strong!
Am I at the safe rpm range or could it be higher? I dont want to break it.
Need some feed back!!!!!!
