whats the max rpm's the factory rotating assembly should be safe at. looking into building a high revving n/a setup. heads, cams, intake, lt's, valvetrain. lighten up the drivetrain a bit too.

What are you doing to it to make it clear a higher rpm? You might be best off redoing internals as well, or keeping it at 6k

this is what youll need.. lighter rotating assembly (optional) head work/porting/polishing and cams with ALOT of lift

my tuner spun mine all the way to 6500 on the dyno @ 10 psi. didn't hurt it but it stopped making power at 5700.. it stayed even till about 6100 and dropped about 10 hp between 61-6500. i wouldn't rev it like that routinely, but on an NA setup i'd say you should be able to rev it to 6500.

6500 will be fine.. but if u wannamake steady hp/tq then you need head work!

You might look into swapping in a 4v bottom end (non-Termie). They're designed to spin 6800+ out of the box, and the weight savings certainly won't hurt.
