Valve spring question
What is the deal with having to warm springs up and then let them cool completely down right after a cam install. Me and a buddy just put a cam in a 5.3 today and wanna know the reasoning behind that.

Go Ls1howto.com and you will find the instructions there. Never heard of it before and therefore you understand why I have a question. As accurate as everything else on there seems to be, I assumed there must be some logic behind the emphasis on allowing the springs to reach full operating temperature and then allowing them to cool down thoroughly overnight.

If you want you springs to last heat cycle them atleast once and never "get on it" when your engine is cold . These performance valvesprings have higher spring rates because of a harder alloy steel being used . If you stress them when they're cold you'll shorten their life dramatically and possibly break them alot sooner them if you take care of them . OEM springs are designed to endure all kinds of situations to reduce warranty claims from abusive drivers . Heat cycle your springs and don't rev your engine till it starts to warm up , you don't have to wait till operating temp but absolutely do not rev a cold engine .

It is my understanding, and this is stressed with new rear end gears also, that heat cycling allows the molecules to "line up" better and will add to the strength of the material.
