Hams2000, are you running exhaust valve springs on intake side? Do you have dyno? thanks for sharing.

You use intake valve springs on the exhaust side not the other way around.

[B]You're better off just upgrading valve springs, as they really help the motor not fall on it's face at higher operation. I was running the Toda cams, but now I am back to stock. I still have my upgraded springs on the stock cams, and I notice quite a difference up top. It used to die off above 8000, but now pulls strong up to redline. Plus, you could run the AEM like me and go up to 10K

I have no "actual" dyno times to confirm my statements. I left the intake springs on the exhaust side when I changed out back to stock cams, and I have noticed that my car still remains very strong from 8000 up, where as it used to really fall on it's face. I will put the car on the dyno this weekend to confirm this.

P.S. you can get stiffer springs from Crower.

Is it much trouble to change out the exhaust valve springs? Is there a "How To" somewhere? What reason would Honda have for putting weaker springs on the exhaust valves? Could the use of Intake springs on the exhaust side reduce the need for the higher valve clearances, or shorten the life of the valve?
