    Stiffer valvesprings

    Okay, so I plan on going with a more aggresive cam. I'll be swapping out my valvesprings, retainers and pushrods for sure. My question is that I hear after you install stiffer springs, you need to make sure the car is fully warmed up good before hitting high rpm's, or else I could go breaking springs.

    How true is this?
    What is "fully warmed up"?
    I don't plan on redlining it that often.

    Not a good idea to beat on any car until it's warmed up. I generally try to keep the rpms under 3,000 till it's warmed up. I've got a TR224 cam with Comp 918s for about 4 years now. No problems.

    with the steel materials that are used to make springs these days, there is no need to get them warmed up. it is a good idea to get the motor to operating temps so as not to scar the cylinder walls.

    Okay, seeing that I don't want to jack something up with my engine, and have no experience with going with a more aggressive cam/springs...how long does it take to get to "operating temperatures"?
