appears to be the superseded part # for a 87 and a 90 truck head, E7, and F0, and given a Mustang designation as F1ZZ-B .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