And if so, do I really want that?
Anyways, thanks for everything you all. You have all been great and i appreciate it all.
Thanks,

when you adjust the cam gears, you will notice a difference in where the engine makes power, more mid-range as opposed to top end.
the type r valve are a little different. the stem that goes through the intake port has been shaved down. offering a smaller frontal area to incoming air.
milling the head will raise compression, and most likely cause more issues since everything else that controls fuel and spark is the same.
and one last thing, even though the two digit code thing is cool, when trying to diagnose an engine, it is quite useless. next time you take it to a shop with the check engine light on, ask them what the (exact terminology) DTC is. it will be something like P0xxx. in your case it would have been something along the lines of P0303, which is a catalyst damaging misfire from the #3 cylinder. but if it were that exact code, you check engine light would have been flashing constantly every time you drove the car.
