=Valve Spring Information=

See the truth about valve springs, [http://www.cpgnation.com/forum/truth-about-valve-springs-2631.html].

'''Considerations'''
* Use a valve spring with correct spring pressure
* Outside diameter fits into hole for spring
* Positively locate the spring to avoid 'dancing'.
* Consider using a spring retainer

'''Proper Handling'''
* Handle with care
* Never place in a vice, grab with pliers, or hit with a hammer
* When separating springs, use a durable plastic object, not a screwdriver
* Do not clean with acidic or evaporative cleaners - can cause rust
* Use proper lubricant to ease assembly

Spring loads can be tested on a load tester.<br>
Shims can be used to raise the spring up a bit.<br>
Once installed, check for coil bind.<br>
Springs need to break in.  Limit initial RPMs (1500 to 2000).
