Very hard to find Marty. I bought a pair from a guy in California who had some sets. If I can find his number I will PM you. I got lucky a found a set on Ebay for Brian O Toole and he found a set also, so I think he has a couple sets, you might want to PM him.

I only bought the one set. I wish I would have bought the other one just did not have the funds at the time. I know they were out of PA.

Good luck with your search as Brett stated hey are hard to find.

what engines do these come on?

Re: wanted - Ford Cylinder Heads
 

I believe they came on 97 Explorers and Mariners, also some marine applications..

Re: wanted - Ford Cylinder Heads
 

They were over the counter and marine applications. They were pre production GT40 heads before the GT40's came out in 93. The Explorer heads were all GT40P's.

Bret,

Are these the same ports and chambers as the F1ZE-AA? I know that AA have GT40 cast on them, but otherwise I think they're identical to the BB. If that's true, it may be worth asking NHRA to approve them.

It's a suggestion which I'm sure won't sit well with some folks.

Re: wanted - Ford Cylinder Heads
 

They are the same head. I mentioned the same idea to Marty. We have done that in the past.

Someone told me that the F1ZE-AA head has larger valves than the F1ZE-B head.

Re: wanted - Ford Cylinder Heads
 

The -AA come with 1.84/1.54 valves.

The throats on a set I have measured 1.64"/1.27", which would give you a 92% intake throat and a 87.5% exhaust throat when using 1.780"/1.450' valves.

In other words, you'd need to change the intake seats because the throat's too big. A 92% throat will work, but 88%-90% is where you want to be for a stocker.

You'd also have to sink the exhaust valve, but there's enough material on the seats to keep the throat at 88-89%. Depending on how much you have to sink them, you may be better off replacing all seats in the heads.

Re: wanted - Ford Cylinder Heads
 

The F1ZE-B head has 1.84/1.54 also. That's the head I had my 92 Mustang SS/LA car.

Thanks Bret!

Re: wanted - Ford Cylinder Heads
 

Bret, I am confused. The F1ZE-B is an approved cylinder head, but the blue print spec. shows valve size to be 1.782"

Re: wanted - Ford Cylinder Heads
 

Yes, we had to take the 1.84/1.54 valves out and replace them with the the legal 1.78/1.45 valves. Just like Sbillison said in a previous post.
