Valve Spring Shims
Changes in assembled height after valve grinding and/or heat during the break-in period can lower the spring pressure substantially. Valve Spring Shims offer a simple method of restoring this lost pressure. Valve Spring Shims can also help protect the cylinder head from damaging contact directly with the valve spring.
