In L-head engines like our Packards it would be a poor idea to fit valve stem to guide clearances at anything other than the original Packard specification. I've replaced more valve guides than I care to think about in these engines and it's rare that the new guides require reaming to provide the correct clearance, but it would still be foolish to install new guides and not check the clearances and ream to size if needed. Tigher clearance is not better.
