Original Jaguar XK 140 XK140 C5718 Intake Exhaust Camshaft Pair MC20889 OEM

OEM Original. Used, may need to be reconditioned, look good but have some marks here and there. Strange thing is that I thought the pair was C5717 and C5718, but both have the same C number engraved. But as many of you probably know the first lobes point toward the side (intake or exhaust) that they are supposed to be on when the tool alignment notch is at the top. Maybe someone can clarify this for me. Please review all the pictures for overall condition and ask any questions prior to purchase.
