I have found a very good and cheap substitute for the discontinued copper core plugs. Autolite makes a copper core 104BP that I picked up for less than $1.25 each and they are running great in my 92 300TE. I know they aren't on the official list, but they are the correct heat range, all other specs match identically and they are definitely copper core.
