Talk about being nit picky. Go on honda tech and type in "stock head" in a search and see how many posts come up with STOCK heads with upgraded valvesprings and retainers. Take the valvesprings and retainers out and it will still make the same power. How high you rev a motor isnt going to make it more power. I can rev my motor to 9k just for the hell of it but my power falls off after 8k. I will bet money that with boost it will have the exact same effect.

How about we go around and say that it isnt a stock head if he has an aftermarket intake manifold or even a turbo manifold. They are the exact same thing as valvesprings and retainers. They are necessary head accessories IF you want to get technical.

Do I have a stock motor???? I have a SWAP header ( required for the motor to fit in the car) and a 3" U bend that you could call an intake b/c the stock intake and air box from the RSX does not fit in my car. Oh wait I have kpro as well, I guess that makes the motor not stock as well.

I think I will walk around saying that I have a BPU civic, I wander how many people will make fun of me for using a supra term...
