=Valve Spring Information=

See the truth about valve springs,.

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. Shims can be used to raise the spring up a bit. Once installed, check for coil bind. Springs need to break in. Limit initial RPMs (1500 to 2000).
