we use Supertech Valvetrain in all our race engines. 10,500RPM all the time. and in our Hot Rod CRX, has seen 11K several times.

you just have to have the proper kit/spring rate for your application. if youre taking it up that high, make sure you have the higher spring rate(I'm assuming you have a B-series, there's 2 kits avail)
