When I was changing my oil the other day I noticed that when I peered down into the valve cover, I had a date code of F1AE, This is in my 1998 Mustang GT. I did some research and came up with some things,
"The '91-'92 Romeo SOHC head sports an F1AE casting number, with a bridge-style camshaft support bridge across the cam journals. These heads have no cam bearings. The camshafts ride right on the aluminum saddles (journals) in a cushion of engine oil under pressure. The cam covers sport nine bolt holes. There are two types of spark plug holes: short-reach and long-reach. Long-reach spark plugs indicate early castings. Later castings have a shorter-reach spark plug. This is important to remember whenever you're swapping heads."

... Does this mean that my motor has been swapped at some point?
