Inner, valve spring (White and red paint dabs)
Inner valve spring for the cylinder head, marked with white and red paint dabs, PN 70-8787 (E8787).
This is the inner valve spring for the cylinder head, listed in the parts book under 70-8787 (older books show it as E8787). It's identified by white and red paint dabs on the coils, which is how the factory kept it distinguishable from the outer spring in the same valve assembly.

It sits in the cylinder head and rocker box area, working alongside the outer valve spring to control valve closing. The catalog places it in the cylinder head, rocker box, and exhaust pipe figures across engines built from 1969 through 1974.
We don't have anything in our records tying this specific spring to a named model, so if you're matching it to a particular head, check your parts book or give us a call to confirm before ordering. One catalog listing we've seen references a triples application, so if you're working on a three-cylinder engine it's worth asking about before you order.
