Inner valve spring

Inner valve spring from the cylinder head and barrel assembly, cataloged as 70-3214 (also listed as E3214).

PN · 70-3214

70-3214 is the inner valve spring listed in the cylinder barrel and head section of the parts books. On engines using a dual-spring valve setup, the inner spring works alongside an outer spring to help control valve closure and keep the valve seated against the cam's timing rather than bouncing at higher revs.

This one shows up in the catalog under the older E3214 number as well as 70-3214, so if you're working from an early parts list you may see either printed. Our records tie it to catalog appearances from 1963 to 1964, which is what we can confirm from the books we have.

As with any valve spring, if you're replacing one it's generally good practice to replace the full set together rather than mixing old and new, but check your own head's spring arrangement before ordering since not every engine in this era used the same double-spring configuration.
