FLAPS is closed today. Rock Auto doesn't list them. Are they difficult to source?

Most common problem is that the valve stems are rusted and not allowing them to move up and down. Penetrating oil and tapping the tip of the valve stem only and not the retainer may loosen them up. Check all of them.
Good luck
The older I get, I only want to work on older rigs.

He found a set from a 216 that are supposedly 1/16 shorter than the gmc. Does that seem to make sense to anyone? Would assume those are incorrect?
