They are not the cheapest on the market, but if you want the best, Ferrea is the way to go. There are 3 Major Issues with stock valvetrain, that can be prevented by using Ferrea Components. BIND - They can "bind" and get stuck, losing their ability to open and close the valve. This is an easily diagnosable failure. Depending on how it binds, it could cause failure to other engine parts.
BREAK - They can "break" into pieces dropping the valve into the combustion chamber and consequently ruining your bottom end. FLOAT - "Valve Float" is a hard to diagnose condition where the valve spring rate is not high enough to fully extend the spring and close the valve after a complete rotation of the cam before the cam comes back around again. So what ends up happening is that when the cam is spinning fast (high rpm) the valve never closes, and combustion leaks out of the engine, and the engine loses power.
