Stockers, look for either E7's, or GT40P's. GT40P's are on V8 Explorers, they're cast with a "GT40P" right on the head next to #1 (and #8) spark plug.
E7's are on any ford 5.0 built from 1987 through 93 I THINK. Don't quote me on the 93 part.
Aftermarket, I'm a BIG CANFIELD fan!!! Canfields are first on my list, then AFR, Trickflow, etc etc. I even had a set of iron Windsor Sr. heads that made awesome power.
