im wondering if i need to upgrade my valvetrain to use JUN II cams in my 2nd gen b16...so far the power makers mod list is as follows...2.5intake, 4-2-1..2.5 collector header, 2.5 test pipe, 2.5 catback exhaust, mugen headgasket, skunk 2 intake manifold..would it be allright to add a JUN II intake cam into the mix using the stock b16a valvetrain and a 8k redline at max?

how safe/reliable would this be?

how dangerouse/fragile would this setup be if i mis-shifted?

thanks
