Dear F-series officianados!
It appears to me that there is no difference in the exhaust and intake valves on the F-12. I bought "a set" of 8 NOS valves from a guy, and to my eyes, they are all the exact same size and have the exact same part number.
Then I pulled the old valves off an F-12 head (with a hole in it, presumably from freezing), and they also seemed all exactly the same and had the same part number.
The reason I ask is because I took the head (minus the valves) in to a maching shop (an hour away from me) to have new valve seats put in, and he said something about needing "both valves". I forgot to bring my new NOS valves with me. I am thinking he was assuming the intake and exhaust valves were different sizes. So, I am shipping him my valve assemblies, and want to indicate to him that there is no difference in the exhaust and intake valves in an F-12 if that is, in fact true.
So I was hoping someone could confirm this. Also, I assume both the exhaust and intake valves are ground at the same angle, right?
Thanks for your help,
Tony
