crower 402t+dual valve springs and ti retainers. safe to rev?
I have a DHR head with dual valve springs, Ti retainers and soon to have 402t's in it. motor is fully built, has wiseco 9.0:1 pistons on eagle H-beams. ARP rod bolts, head and main studs etc. Im just wondering what this motor can SAFELY rev to and what the cams make power to? I have searched archives and threads from a couple years ago, reading about people "thinking" the head would safely rev to 8500-8800. But then crowers side(which doesn't even show 402-t's) says that other 402's are safe to 9+ But would like to hear from someone with experience before I go out and start tachin my **** off that high.
ps... if it really does rev anywhere near that high, uber baller status coming from an LS head

Re: (JadeGreenEF9)
There's no point to revving them past 8000 since they won't make power past that. If you have an IM, TB, P&P head, etc.... then hit up a dyno to find where you're power band is. No one can tell you if you don't have a stock head

thats part of the question im asking, is what other people are revving a set up like mine, and still making power too. I have no idea what these cams make power too on even a stock LS head. Mine has a skunk 2 intake manifold, bored throttle body, hondata IM gasket, 5angle valve job, and mild P&P. Anyone else running a similar set up? If so care to inform me?
