don't mean to steal your thread but i thought of an additional question. i ran a wet kit on my 5.0 and ended up fouling the plugs. i went with the colder temp plugs like you were supposed to and i would also have some small detonation i could hear pop in the intake. is it totally safe if you play by the rules in the s197 or will you always be fouling plugs and risking detonation no matter what?
