After reading everyones posts, I have come up with some things:

1: 15Austin-----You are a complete ***. Does that 15 stand for your age? An adjustable Fp regulator is VERY important when you install heads, cam intake combos. And even more important when you install bigger injectors.
2: ok, I withdraw my last statement on Mass air conversion. You might wanna consider it in the near future, But I agree with Zach. You need to change it.
3: Ckyguy is right, just mess with it. i didnt even have to take my rail off to switch it. It takes some work, but anything thats worth anything takes some work and maybe a little trouble right?
4:You must install longer pushrods when you do a TW head install. You have to measure to see how long you need them to be. Stock ones wont allow the valve to open up totally, thus holding your power level at a minimum.
