Redline information.
Redline on a given engine is based mostly on the camshaft and mechanical limits. The most important redline is based on the mechanical limits of the engine structure and valve train. You do not want the rods to fly out or the valves to float. The camshaft grind determines the second redline which is based on the breathing and efficiency characteristics of that cam. In other words beyond a certain point you are getting diminishing returns in torque and HP. Redline is usually set at just beyond the HP peak of the engine where the HP starts to drop off rapidly.
To increase the redline in an engine they are balanced and blueprinted with a better valve train, breathing, and camshaft. When you do this you may also loose low end power and torque which can cause drivability problems in a daily driver.
For more information check out the Performance engine building section and the 460 engine forum.

Is the engine stock?
If it is, -probably 4500 rpm
They will turn a little faster but it won't do any good.
You can enter your engine specs in a dyno program to see the HP and torque curves or you can check the max HP @ rpm for the engine listed in many repair manuals and add 500-1000 rpm.
