Stock valve stem seals?

Hey there, gents! I'm trying to track down some valve stem seals for a 250 2v head. Do you folks know what they came with stock? I've tried installing 11/32 rubber umbrella type seals, but they make a disconcerting clicking noise that just doesn't sound right...
 
They came with a hard plastic umbrella type seal. When I was doing my apprenticeship at the Ford dealer
we would replace them with the soft rubber type used on the first Cross flow 6 Engine. This was usually
done because the originals were worn and causing smoke on start up.
