When valves have been removed for inspection, reconditioning or replacement, valve springs should be checked against specifications for free-length, spring force and spring installed height. Refer to ENGINE SPECIFICATIONS .

Installed height of the valve spring must be checked with the valve assembled into the cylinder head.

If the valves or valve seats have been refinished and the installed valve spring height is greater than 41.0 mm (1.61 in.), install a second spring seat in the head counter bore under the original valve spring seat to bring the spring height within proper specification. Make sure the measurement is taken from the top of spring seat to the bottom surface of spring retainer.
