The stock Chevy retainers are made out of cheap low-carbon steel. Low-Carbon steel works for production street cars but is inferior for racing applications. Our chrome moly “Look-A-Like” retainers will not break.

Bulletproof your ‘602 Crate Motor Valve Train

Every racer who runs a ‘602 crate knows the valve train, especially the valve springs, are a real problem.  The stock valve springs are too cheap and too weak for circle track applications.

On the ‘602 crate motor, we are concerned about the valve spring pressure, or lack thereof, on the intake valve.  Why the intake valve and not the exhaust?  Well, the intake valve is heaver and will “float” before the exhaust.  Anything you can do to increase the effective valve spring pressure will help keep the intake valves out of this destructive “float” condition.  The “intake valve float” condition is problematic because the stock Chevy ‘602 valve springs suck, especially if you are trying to run the motor over 5,800 rpm.

Install our “Look-A-Like” valve springs, retainers and locks and you will not have to worry about valve float again.
