Ford 302 questions
I'm in the process of building a new motor for a 1989 Mustang and wanted to know is it worth looking for the below Cylinder Head? If so does anyone have any leads on finding them as I have tried searching the net with no luck. I think I have a lead on one head at a cylinder remanufacturing company but that is all at this time.
F1ZZ-B Also is there any difference in the below intake manifolds? E7ZE-CB Aluminum Upper E8ZE-EA Aluminum Upper F0ZE-AA Aluminum Upper |

Re: Ford 302 questions
Buy them, try them, put them on a shelf. With the cast ones that's how it worked.

Re: Ford 302 questions
I looked into this part# quite a long time ago and had one of my Ford dealer try to track it down....the F1ZZ-B wasn't a valid number for a 302 head and didn't exist. The only legal head I know of available is the E7TE in stock.

I’d love to see a picture showing these beads actually exist.. I’ve spent years looking talked to many ford contacts and have never found the number to be legit. At one point the only feasible suggestion was that they were used as a replacement only head at the dealerships at one point.. which made no sense. To me it might have been a paperwork number that was never cast on an actual cylinder head.. we gave up on attempting to find them and went another direction.. So I’d love to see an actual picture showing me that number was cast into a head and I didn’t totally waste those years looking haha |

Re: Ford 302 questions
The fourth position in a Ford casting is a "group" ID. Z is factory replacement and E is "engine group" (original part).
F1ZZ and F1ZE should be the same head. F - '90s 1 - 1st year of 90's Z - Mustang '91 Mustang cylinder head. This might help. https://www.enginelabs.com/engine-te...sting-numbers/

Re: Ford 302 questions
Ok ,,, Looks like the part # F1ZZ-6049- B does exist as found in the
Obsolete - Supercede - Interchange Manual FPS 7632-5 January 1994 http://www.fordpartswiki.com/getpage?pageid=158340 http://www.fordpartswiki.com/getpage?pageid=158516 appears to be the superseded part # for a 87 and a 90 truck head, E7, and F0, and given a Mustang designation as F1ZZ-B .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.. |
