Hello All - I have a general 302 question.

Did the 1994-1995 Mustang 302's ever come with aluminum cylinder heads? I'm trying to settle an bet with a work buddy of mine, and if someone knows the answer (or has a link to a credible resource so I can claim victory and win a cup of coffee), I'd appreciate it!

I looked thru the forums and couldn't sort out the answer.

Page 204 - Cylinder Head History and Highlights

"The 1987 - 93 H.O. heads carry either an "E5TE" or "E7TE" prefix, the later being the most common Mustang head in 5-liter service." .... "The E7TE casting was also used on 1994 - 95 Mustang H.O. engines."

Page 211 - Aftermarket Cylinder Heads, Aluminum Heads

"In mid - 1994, Motorsport SVO/FRPP released an aluminum version of the GT-40 cylinder head."

Cast iron was all of it.

Steel... cast iron.... it's just a 1-2% carbon content difference... hahah.

Like I tried to say w/ steel....

they never came with aluminum.

Holy Smokes- you guys know your stuff. Now that I've got bet won, I'll for a double-or-nothing wager based on the performance difference of the aluminum/iron difference.

Last Question: what intake/exhaust valve size did the 94/95 302's come with?

This is just for a cup of crappy cafeteria coffee, but the thrill is in the win.

Heres your specs on the 94-95 302. 1.94 intake valve and 1.54 exhaust valve.

AdderMk2

incorrect

1.78" intake and 1.46" exhaust

GT40's didnt even have 1.9" intake valves

Use answer from Adder for that cup of crappy coffee.
