Valve guide for the Trident engine, listed under PN 70-6420 (also found as 70-0343 in older books).
70-6420 is a valve guide for the Trident engine. The old parts book also lists this one under 70-0343, so if you're working from an earlier catalog and see that number, it's the same physical part.

A valve guide is what the valve stem rides in as it moves up and down in the cylinder head, keeping the valve aligned and giving it a wear surface separate from the softer head casting. Since this catalog entry is brief, we don't have more detail on it beyond identifying it as a Trident guide.
If you're doing head work and need to confirm which guide goes where, give us a call before ordering and we'll walk through it with you.
