6000 or so, its gonna run out of head and intake, regardless of max rpm

6500 is fairly safe if your not doing it everyday and pointless if you have stock heads/cams. I would say anything up to 6200 will be safe everyday.

RE: How high can I safely rev on stock internals

I think I have my fuel cuttoff at 6200 RPM. I don't want to see any more than that. I try to shift right at 6K or a little earlyer.

On your setup though its pointless to rev more than about 6000 anyway. N/A the stock heads and cams are really falling off at that point.

Even at full boltons you can see how the car is starting to fall off on my dyno:
