Being a HFT cam, I cant really recommend a good spring. Most of what I know relates to HR's. What happens if you dont have the right spring is the valves will bounce back off of the seats when they close. That can be worth lots of power.

In the next couple days I'm going to post one of my dyno graphs. I have the hard drive out of the computer that used to run the chassis dyno here locally, I just need to put it in a computer and transfer the info over.
