PRC 660 springs Well I think my springs let loose because I have some noise on the pass side valve cover and those springs are like brand new not even a 1000 miles on them. Has this ever happen to anyone with these springs? I bought them from texas speed. I'm going to pull the valve covers off wed or thurs and see for sure. I am getting miss fire readings and it say its #3 and #6. let me know what you think. thanks
Pull a cover and check it out. That's a big jump to a conclusion without anything but a sound to base it off of...could be a rocker arm that spilled its beans, broken valve, dead lifter, etc.
Let us know if it's a spring and of course we'll do everything in our power to take care of you though!

Please explain why because most of us on this board practice this. In fact I have been practicing this for 25+ years with my Gen 1 stuff. Please provide RESEARCH & DOCUMENTATION with your reply. I have just been doin what I was taught
It does make sense in a way as engine temps are much lower than temps required to temper steel

I can not provide documentation/test results as it is proprietary to the manufacture. Only my experience from running the dynamics/durability lab at a major spring manufacture.
The more temperature they see generally the more load loss will occur, but heat cycling them isn't going to increase the life of a typical aftermarket spring. Keeping them cooler will though (oil sprayers/flooding the valve covers).
There is no "break in" procedure for a valve spring. 99% of failures are from:
-Over stressed Design or improper material/processing used.
-Bad dynamics causing a over stressed condition (wrong spring used).
-Manufacturing Defect.
-Handling Damage.
That's pretty much it. Heat cycling/"breaking in" the springs will do nothing to help with these failure modes, but it won't hurt it either I guess.
You pretty much answered your own question.
