COMP Cams 4779-8 - Rotator Eliminators CB Exh

Valve Spring Shim - 0.300 in Thick - 1.732 in OD - Steel - Big Block Chevy - Set of 8

Avoid stacking .300" of shims under the valve springs on your Big Block Chevrolet with our seat spacers. These spacers feature a 1.732" outer diameter for 1.568" outer diameter springs.

The old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams offers a simple but effective solution to this problem. These Valve Spring Locators provide a thin, hardened Steel alloy seat that will not only protect the head and shim, but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup so COMP now offers an ID locator with the locating shoulder on the inside, as well as the spring cup.
