Big Block Mopar Heads
 
I have several sets of 906 casting heads. They all have the letter "F" or "C" cast into them on the underside of the head. Do these letters mean anything?

I am not sure what the F or C mean, but I was told by one of the premier big block guys on the West Coast that the F head flowed better. Of course that was pre acid days.
