Re: Valve guide dimensions? Bronze valve guides?

Hi Jack: I've never seen bronze guides in any Packard engine as manufactured though they may have been used on the very very early cars. But a local engine rebuilder here of considerable repute uses them routinely in engines that have cast-in intergral guides, including Packard V8s and others. He much prefers that to reaming the guides oversized and getting valves with OS stems.
