I've always seen different valves for intakes versus exhausts from the factory in all the 32-48 engines (from the factory). Now, I'm sure there are many cases where this doesn't hold up - but generally it was true.
With that said - I've taken apart many rebuilt flatheads where all sorts of intake versus exhaust combinations were used - so I don't know if it actually makes any difference. I don't know if there were different alloys or material properties between the two different valves from Ford.
Anybody know the details?
