289 HP heads

[Digdug]

I'm in the process of restoring a 72 bronco and it had on it a pair of 289 HP heads. I did a bit of research and it looks like they were originally off of a 68-69 mustang? Not 100% sure on that. The original engine was heavily modified.

Does anyone know if these heads are worth anything? I have a few parts I plan on listing in the for sale section. Thought I might ask here first if these would or should be included as bronco parts for sale since technically they are from a mustang.

My 73 had 289 heads. I just assume it was a 289...?? It got replaced with an Explorer 5.0.

The engine was a 302 but it had these 289 High Performance Heads on it.

Well I was trying to attach an image but I can't seem to get it to work.

Hi, HiPo 289 heads have casting # C5OZ-6049-B. They were cast with slotted pushrod guide holes, and a spring seat boss, which can't be duplicated. Also screw in rocker studs. Good luck

Hello, thanks for the reply. These have a HP marking but the stamp code is different than what you listed. These have C8ZE-B and a HP 3M2O markings. There is also the numbers 61375 in a circle. I'm not a gear head so all this is kinda new to me. Thanks again for any info.

My block is from the 60's, and I've read that they used those blocks into the 70's. So without measuring stroke, how would we know that it is/isn't a 289?

This truck was bought by my grandfather new in 72. I have the original 302 heads, intake and all that he took off. I'm not sure why he put 289 heads on a 302 block and unfortunately he's not around to ask. I know it also has a 4 speed mustang trans. I think he originally had it set up for hill racing. I remember as a kid the thing screamed.

Urban legend has always given the Hi-Po head larger ports and valves than other small-block Fords, which has never been true. Valvespring pockets for stability and screw-in rocker-arm studs for dependability make the Hi-Po head unique, because the more common press-in studs tend to pull out with aggressive camshafts and high revs. Outside of these factory modifications, the Hi-Po heads are virtually the same as the 2V/4V heads. Spotting a 19, 20, or 21 cavity number in the corners of the castings outside of the valve-cover areas on the exhaust side quickly identifies Hi-Po heads.

Casting numbers C3OE, C4OE-B, C5OE-A, C5AE-E, C7ZE (service head), and C8ZE-B (also a service head). The C8ZE-B service head does not have the two-digit cavity.

seems like the 289 heads, in general, had a smaller combustion chamber too, didn't they? that raises compression and as Digdug says, makes them scream...

54.5cc as I recall......

I'd probably have better luck selling these on a mustang forum or something like that if they are truly HP heads. Would anyone recommend I get them redone first or just cleaned or simply sell as is? Thanks again for all the info. Any idea on value?

 

[Boss Hugg]

I would let the buy have them built to his own specs. BUT..Price high so you can come down and not give them away. Old iron is hard to find...

 

[Digdug]

Thanks for all the info. I'll do some research and figure out what would be a decent starting price.

 

[Rustytruck]

Their worth some money. I would clean them but that's it on your part. If you were down the street from me I would give you a couple of hundred dollars for them just because of what they are. The cost of shipping is a problem with heavy parts. You can plop them on E-Bay and see where it goes. They are not a wise use of money since the aluminium Edelbroc heads are so much better flowing right out of the box.

 

[Boss Hugg]

It's too bad they cost so much. Someone trying to run a Ford on a dirt track stock car might want them... BUT, alas, they say it costs too much to race a Ford... (I see people around here paying $400 for a pair of unworked GM heads and then spend $400 more having them built. because they have to run STOCK heads. Silly shevy's.

The audience for the HiPo heads (if they truly are) will be the period correct Mustang guys. The guy who has a HiPo stang and the heads are long gone and he needs them for his restoration.

To the RIGHT guy they're gold........Finding that right guy might be the issue....

That's the casting number C8ZE-B and the 289 has two dots above it. I'm not sure how else to confirm they are. I'll look around some of the classic mustang sites/forums and see if I can find someone who is interested. Thanks again for all the info. I tried posting pics of the heads but it didn't seem to work.

They're good heads like has been said. I'm running them on phred. Reason being I had them and at the time when i built the engine a pair of aluminum heads was still ridiculous.

Those are real Hi-Po's, I can see the raised ridge for the valve spring. Looks like a 3H20 date code which combined with the C8ZE-B casting number probably means these heads were cast in 1973. Restorers want date codes and casting numbers that match their cars so these won't have the value of earlier heads, still worth a bit of money though.
