    Big Block Chevrolet Seat Spacers

    Late model Big Block Chevy engines are originally equipped with exhaust valve rotators. Until now, the only way to make up for the rotator was to stack .300" of shims under the spring; this sloppy at best. Comp Cams Rotator Eliminators will locate the spring with an outside step so the spring cannot "walk" around on the head.

    Old standard shims will not hold up to the extreme spring pressures & high RPM of today's race engines. Comp Cams offers a simple, effective solution to the problem. These valve spring locators provide a thin, hardened steel alloy seat that locates and holds the spring in place while protecting the head and shim. Previously this part had only been available in a cup form with the retaining portion on the outside, which required the head to be machined a great deal to accept the cup. Comp Cams has an ID locator with the locating shoulder on the inside, as well as the spring cup. Spring ID locators can usally be installed without machine work.
