I contend that hte valve guides starve for oil

I think you'll find and perhaps JV will respond in more detail that there is a very wide degree of variation in original V8 engine life, some going well beyond 100,000 miles with no problems, and others with problems very early on, perhaps at 40,000 miles of thereabouts. Some of this may be due to how dedicated dealers were in making changes like the several changes to rocker shaft oil holes, and just how well thought-out those changes were in the first place. And of course another variable is the care the engine received from the first and subsequent owners.
