Valve Springs
- Valve springs are installed with enamelled end facing rocker arms. Inspect valve spring pressure and free length. Replace spring if it is not within specification. See VALVES & VALVE SPRINGS table under ENGINE SPECIFICATIONS.
- Measure valve spring installed height from spring seat to bottom of spring retainer. If spacers are installed, measure from top of spacer. If height exceeds 1.74" (44.2 mm), install a 0.030" (.762 mm) thick spacer in cylinder head counterbore to obtain correct installed height. See VALVES & VALVE SPRINGS table.
