390 FI Heads?

Ok, here is one for Rob, Arlie, Neil..etc.

I had the heads pulled off my 390 recently, to find out exactly why I was getting little to no compression in three cylinders. Good news was the heads were completely free of cracks and any other issues. Bad news, which was expected, that the valves, springs...etc needed to be replaced. I had the heads sent in to a local guy and they just came back yesterday. My mechanic relayed to me what the head guy said, which was that I have a set of FI heads, not FE heads. He says they are very rare, and that if they ever do crack, that they will be extremely hard to replace, if at all.

I've done a little research on the internet and cannot find anything about FI heads so far. Can one, or more of you please educate me on what I am being told? I may have heard the guy wrong as well. I will be swinging by the shop tomorrow to take some pictures and get the part number from the heads.

Thank you, in advance.
