^^ are you sure you know what your talking about?!?!? Sure you can take them to 8k go as high as you want to
. If you've had enough seat time you would know and feel the cams power band. There's nothing to gain by taking things to 8k on a stock head and setup. The more change you make to the head, cams, springs the more you can push it. Even with my bc272's I didn't go to 8k I would shift around 7300-7500. All I'm saying is its better for your e.t. And mph to stay in the power band instead of trying to push the rpm's past there efficiency range. But do whatever you want its your valves that are at risk of damage not mine! Lol
I have no idea who to you are talking to about setups. If you are talking about me, my setups way beyond yours and if you're talking about the OP you would have seen my comment to him about a lower shift point would help his times.
Look up what the stock springs will hold up. Maybe you'll learn something instead of assuming it'll "damage" something.

well besides me going for back road cruises and such
