OUTER DIAMETER! It's the outer diameter that is the major question. If the old guide was larger diamter (OD) then any replacement guides made for that Packard engine mite be too small. Likely that a former rebuilder of the engine bored the engine to accept a guide from some other make of engine that used a larger diameter guide.

Mite even need to check the valves to be sure if they are valves made for a Packard engine. Stem diamter of valve???
