    This is the head pecking order made up by Paul Kane from Charlie Evans on the 460ford.com forum.

    13. Cast iron D3VE-A2A
    12. Cast iron DOVE-C
    11. Cast iron DOOE-R CJ
    10. The various Edelbrock heads, the older Ford alum, A-429 CJ heads, the TFS CJ head, and the Blue Thunder CJ head (stock exhaust port location)
    9. The Blue Thunder CJ raised exhaust port (Ford) (a little better)
    8. The Blue Thunder with Chevy Ex flange.
    7. Ford SVO SCJ head(Kasse)
    6. Older TFS or Ford Motorsport A-460 heads
    5. New TFS A-460 heads, EX514 head, & IDT Eliminator "A" head
    4. Older Ford Motorsport bastard Pro Stock heads
    3. New Ford SVO C-460 heads, & RFE Profiler "C" heads.
    2. D-460 & E-460 Pro Stock heads; & Blue Thunder "Thor" heads,
    1. Then the Hemi heads.

    (As once laid out to me by Charlie Evans. The grouping by family makes good sense, though...)

    Do you mean D0VE or D3VE?

    Of course it all depends on what your doing, build, and what you're expecting performance wise. I'd say most 460 builds, in your average lake boat, a pair of d3ve heads with some nice port work and a really good valve job will work anywhere from "just fine" to "great"... it all just depends on what you have to work with, what you are trying to acomplish, and what your expectations are that really determines whether they are "the worst" or "exactly what you need".

    There is defenatly room for improvement on the stock heads, but like I said, port work, valve job and the right cam for your combination and goal, and you can make them work in most intances... or at least more times than not for your average lake/river boat.


    Just my 1 1/2 cents.


    Btw... what do you have to work with and what are you trying to acomplish anyways?

    Yes they are from a 1970 motor. But from reading the later posts me thinks you have 73 heads (D3VE), these are the heads that I have on my Sanger and are actually a pretty good head So I've been told. The weak link in Ford motors are there heads, they do not breath at all. Just as Six-oh-nine said with a good P&P and valve work you can completely change the attitude of your motor.

    Look closely at the casting number on both cyliner heads. It must be D3VE-A2A; there never was a D0VE-A2A; only D0VE-A, D0VE-C, and D3VE-A2A.

    Long perceived as the "smogger head," it is now possible to get good power from D3VE's. The D3VE intake port architechure is very close to the D0VE, and once these heads are ported either casting (D0 and D3) have about equal potential these days.

    Which head you start with depends on the needs of your build, etc. For example, if you want to simply remove the heads, port, and then reinstall onto a bone stock engine....power will be somewhat improved you will still have a dismal 7.7:1 compression ratio. In such a case, a D0VE head swap might be more benefical since you'll get ported heads and a compression ratio increase to about 9:1. On the other hand, if you are rebuilding your engine and replacing the dish top pistons with flat tops, then the D3VEs will net you about 9.5:1 compression ratio and the porting takes care of the rest.....up to a point. We use D3VE's in builds to about 400-450 hp (more hp is possible but additional head work is required). Again, it depends how much power you are targeting, what you will have for induction, whether your exahust is thru-transom or OT headers, etc.

    So it's the most common 429/460 head out there, but not such a bad head under the right circumstances. I have them on my boat and it runs in the mid 80's.

    U GUYS ROCK... OK, well I'm pretty sure they said DOVE A2A, but i will check again. I'm not building a race boat, just a fun decently fast lake boat. I don't know much about what i have going on seeing how i bought the boat with the motor in it so I'm gunna be posting here as i tear it down. The motor is fairly stock as far as i know, i know it has a pretty big cam in it(is what i was told) gunna find out exact and go from there. Being a budget build i would like to keep the coast down as much as i can. I'm gunna do the port work on my own(i have done this before) and would like to keep these heads if i can but a head swap is not outta the question. I have a torker 2 intake and running a holley 750 mec secondary single pump carb, i want to change that up some too. Would like to go to a tunnel ram if i can find one. But any info is always helpful, i know
    (LAKES ONLY) knows ur stuff and everyone with FORD help goes to you so i appreciate all your info. So thanks again guys and keep the info coming.

    you better research a t/r before you spend any money. looks great, but it,s made for high rev,s. A good single (your intake) may work better for you.

    Which ever of the two heads you have, with correct porting to a Cobra Jet flange, you can build a lot of power. Check out Lakes Only's web site and follow his advice. Also check the 460ford.com web site for engine builds and porting guidence.

    cobra jet intake side? confused me there for a second, never herd of a d3 head ported to cobra jet sized intake ports, or if there was even nuff material there to remove to get to that size.

    Dare to be different, if it turns out great you can claim you planned it that way.

    It can be done, not necessary in most cases.
