Cheetah valve body... Throw away spring?

When you use a valve body such as the Cheetah you used they figure your after ultimate street performance so that's why they say to toss the spring. Remember this, no matter what the factory used when they built an engine, trans, rearend, whatever, if your modifying it with someone else's part you should generally do what they recommend. After all they re-designed things to work differently than the factory meant it for.
