Original 93 Cobra had F1 castings.The chamber is 61-63cc.The 3 sets of 96 Explorer heads I have had no smog holes drilled.Not saying some might of but in my experience they were not.94-95 Cobra heads did have F3 castings as did the lightnings.

Hmmm,well,from everything I've researched there seem to be a lot of variations on them.I cc'ed mine,and they came out to 63 cc's,but they are in the machine shop getting milled down .030 at the moment.:evilgrin:
