Now that the conversation of redline is being brought up.. can someone explain to me what all is needed to be able to rev up to 10g. I know u need new valve springs, but i'm sure there has to be more things added to be able to rev to 10g safely. Can someone tell me what all would be needed to do this the right way and an estimated price on what it would all cost. THANKS
