 Bulletproof Your ‘602 Valve Train: Every racer who runs a ‘602 crate knows the stock valve springs are a real problem. The stock Chevy valve springs lose a lot of pressure after just a few nights of racing.

On the ‘602 crate motor, we are concerned about losing the valve spring pressure when the stock springs go south.  When the spring loss a significant amount of pressure, the valves will start to float.  This not only causes the engine to loose rpm and power but also very damaging to the valve train.
