I have a pair of Boss 351 heads. The part number on them is D1ZX-MB. I beleive these are the real deal from the research I've done. I also have new in box Ferrea valves for them.
Here is the thing. I planned on getting them milled, valve job, viton seals and some mild porting. This all comes to about $1000. ( I have detailed prices). Now you can get nice CHI or AFD aluminum heads for a decent price.
Rather than spending close to $1000 on my iron heads, I thought maybe I would sell them and use that sale money, add to it and get some aluminum heads. This should cost me less than the $1000 out of pocket.
My feeler question is:
Does anybody want to buy a set of D1ZX heads?
They haven't been molested bad. They still have 0.060" deep half circle notches on the edges which indicates they haven't been milled much if any.
If someone is interested in them you can email me at email@example.com (if you want to remain hidden from this forum) or simply reply here with your offer.
I'm in Michigan 48386 zip code. Shipping would be on you of course.
What are your thoughts? Does this sound like a good plan to sell mine and buy aluminum?
This would be for a 80% street, 20 % strip driven car. Total yearly mileage has been about 5-6000. Not a daily driver, just a fun 68 Mustang.
Some restorer may pay more then that. For a function over form guy I think it is the right move. Somebody trying to put a Boss 351 back together is bound to want them and be willing to pay the price and then some. You might be able to sell for almost what the new heads will cost you.
you sure they're not service replacement heads for a b 302?

the boss 351 boys say that b351 heads are plain old D1AE-GA that were factory milled for studs ,but that they have "appropriate" date codes for the particular vehicle in question.
Do your heads have a small bolt hole right under the valve cover rail that is already tapped ,in the front ? it's about a 5/16 . do they have water ports on the manifold flange ?
In any case can you send me pics ?
I have some service replacement heads for a b302 but I think they are D1ZE ??
he says that they are real boss 351's because of that D1ZX say's the MB doesn't change anything but that most b351's were D1ZX-AA .The b302 service replacement is D1ZE-AA As I recall I'll let you know later if you're interested .
BTW this runs contrary to much of what I have personally read over on the boss 351 website , so we need pictures !
they won't peform any better than the standard 4v closed chamber heads. The purists would be all over you for hacking on them [porting].
So is their a price war between Afd and Chi? What kind of prices can you get, delivered to your door?
I purchased service replacement heads for a Boss 351 back in 1973. The Part # is D1ZZ-6049-B the casting # is D1ZE-6090-B. I still have these heads on my car now. They came machined for the screw in studs (just like the Boss 351 had) also no water passage for intake manifold (unlike the Boss 302 head). I bought them empty for $100 each.
If you got bare heads in 1973, they were still building Clevelands then. Boss heads would be a simple over the counter item. I wonder how much a pair of N.O.S. Boss 351 heads cost today ?
I can take all the pictures any one wants. Any special part you want to see? I know they don't have an antifreeze hole, they aren't Boss 302 heads, these are Boss 351.
How much do you think I could get for them?
Roo, I haven't priced anything yet. This was just a thought I had and that is why I put the feeeler post out there.
Has anyone received a to your door price for CHI or AFD heads? If so. how much and where from?
Boss 351 heads are rarer. All depends components, condition and buyer. As you pointed out, reconditioning isn't cheap. It's cheaper for the buyer to purchase completed heads. Last year I paid $550 on eBay for 4V '70 CC heads, with new SS valves, roller springs, moly retainers, screw in studs, guide plates, cleaned, magnufluxed, milled and valve job. That's like paying for labor and getting all the parts for free.
I bought the heads from a friend who is on this forum. Before I sell them at a profit, I'm going to offer them back to him at the same price I paid. If he doesn't want them, I'll sell them and make some $$$.
I didn't intend to buy and then sell them. I intended to swap my 2V open for these. Now That CHI has new 2V heads, I'm leaning that way.
I also have a Boss 351 Ford aluminum intake. It is the rare DA one. I was going to use that with the heads. I have a Performer 4V too ...
If I buy the CHI 2V heads, I'll have to find a better intake. I have a Performer 2V presently on the engine. I also have limited hood clearance. An X-Celerator is as tall as I can fit in there (I had one and sold it aaaarrrrrggghhh now I need another one).
I need to hear from the guy i bought the heads from before I sell them. I'll email him now.
we're gonna have a picture I.D. section for all the iron heads . We need pics of whatever makes your heads unique ,the casting numbers for instance, and anything else you see that is in any way different .
You should have three options for manifolds: Weiand X-Celerator #7516, Offenhauser Port-O-Sonic #6122 or Edelbrocks Air-Gap [not sure of the carb pads height].
One thing to think about is the Weiand is preported and the ports are larger than the stock 2v openings in the head. [who wants to get stupid with the grinder on new heads?] I'm also not sure if Afd's and Chi's 2v openings are the stock 2v size or are they larger?
The Offy is said to have stock 2v openings [not getting stupid with the grinder on new heads] I know a stocking dealer in Cali who qouted me $222 for the #6122, is that on par with a new Weiand?
They're higher than hell on everything. A guy at Pate wanted $500 for a set of regular 4V CC heads - I walked on those. Real live 351 Boss heads are worth more than regular 4V CC heads, but the premium would have to be paid by the right buyer.
I'm going to try for the sky. I'll ask $1200 with new Ferrea valves in addition to the factory valves. Some purist on Ebay may bite.
If not, I can re-list at a lower price.
It doesn't hurt (much) to try...
