37 and 47 valve guides

[stan]

Does anyone know if the 47 Chief guides will fit the 37 engine. Gerry Greer has different numbers, so there must be some difference., but what. I need to go through my 37 someday, and there are some guides on ebay for the 47 Chief. Thanks stan

They are different.
The 37 has two less fins under the seat so the machined smaller diameter that goes in the cylinder is shorter,more guide exposed.
