How high would a car like mine rev to safely? I was racing a friend and noticed that a was a little bit above the red line. It made me a little uncomfertable but does the redline on the tach actually reperesent the true redline? My car has some engine work done but id still like to keep it safe rather than blowing something up.
 
6000rpm is no problem for this motor if you have adequate oil pressure and it is basically sound. Valve train is the limiting factor. I see you have upgraded valvetrain so you should be good to 6000-6200. Most likely it stops making power at about 5500.
 
With stock valve springs I'd be worried about taking it that high. In fact I just wouldn't do it. ;) If you have upgraded springs then it shouldn't be a problem.
