Valve spring—outer
Outer valve spring for the cylinder head, part of the pair that closes each valve on the return stroke.
70-8114 is the outer valve spring, one of the pair that closes each valve in the cylinder head. This one sits over the valve stem with the inner spring inside it, working alongside the valve, collar, and collets to keep the valve seated between cam lifts. The catalog carries it under the pre-1973 letter-prefix system as E8114, which is the same physical part listed under the older parts-book numbering.

It shows up in the CYLINDER AND CRANKSHAFT and CYLINDER HEAD, BARREL AND CRANKSHAFT figures, which is where you'd expect a valve spring to be listed since head and top-end work get grouped with the crank sections in these older books. Our catalog entries for it span the late 1960s.
Valve springs are a wear item — they lose tension over the years and running with a soft spring can let a valve float at higher revs. If you're rebuilding a head it's worth checking spring pressure or just replacing the set rather than reusing old ones. Beyond that, we don't have more detail on this one in our records, so give us a call if you want to confirm exactly which head it fits before ordering.
