Ok ,,, Looks like the part # F1ZZ-6049- B does exist as found in the



Obsolete - Supercede - Interchange Manual FPS 7632-5 January 1994

appears to be the superseded part # for a 87 and a 90 truck head, E7, and F0, and given a Mustang designation as F1ZZ-B .



Curious to know what it looks like, NHRA tech sheets has the casting # as F1ZE- B , however, I don't see any published runner volumes , valve sizes, chambers, etc...

Steve, I PM'd you. The runner volumes are the same as the F3ZE head 145 intake 55 exhaust.

Glancing at this quickly it looks like the E7TZ-6049-C was replaced by the F0TZ-6049-C and then finally the F1ZZ-6049-B follewed by 2 part numbers that look to be valve stem seals.

For some of the people who may be a little better with ford part numbers what is the significance of the final "-C" and "-B"


I ask.. because the E7 head that is legal is not a "-C" as listed in this OSI book...it's a "-PA"

The second reason I ask it that I have come across a couple sets of F1ZE-AA heads which are the early GT40 heads before the GT40P head (which I believe is the F3ZE)

The way the blueprint reads the "F1ZE-AA" is not legal.. but maybe I just don't know enough about all this and its all the same thing.. I also beleive the F1ZE-AA head has bigger valves than the E7TE-PA head..

Those letters are there for some changes that had been made they start off with an (A) and can go as far as (Z).http://www.mustangtek.com/FordDecode...ecastingnumber
