Just wanted to first say thanks for making the Stage 2 head available now, I noticed it on your site about a week ago. After seeing it I am now saving up and already know where I will be blowing my tax refund check. I wanted to ask a question or two about the package also though. First with the head, does it come with larger valves and stronger springs? Second, is their a core charge or am I able to keep my original? Lastly with the head, would I be able to purchase a tune from you for it [if so, how much (using SCT XCalibrator 2)] and the rest of my mods? This way I would have something to run my car decent until I am able to get it to a local tuner. Thanks for your time and THANK YOU for making the head available. The only bad part about the head being available is that I have to explain myself to people when I randomly shout-out "I'M GETTING HEAD." Thanks again.
