    Default Aluminum heads

    I think I already know the answer but due to my engine budget constraints have to ask anyway....

    Has anyone ever heard of Terry Walters Precision Engines???
    http://www.waltersengines.com/

    Has BBC aluminum heads for $1495... Are they just more Chinese junk?

    I would be very VERY sceptical. Flow numbers aren't very good for a 320cc port. Sure as heck isn't made in the US for that price. I would call them and ask as many questions as you can.

    Same ole POS as the Pro Comp. Same head, same country of origin, the same dickhead marketer. He just wholesales them out to too many ventors to even keep up with.

    These guys are no better. Want to market a rod or crank under your name, these are the guys to talk to. We got your cranks, your rods, your rockers, dampers, and now 351 W Ford blocks. We can set you right up. Alas, you are able to built a 351 W without using a sigle USA built part.

    I sent an email asking if that price was for each or a pair.....

    Here's his reply..

    Hello Boat Man,
    They are for a pair. We are now offering a fully CNC version for $1950.00 a pair .Thank You Terry

    I guess if I want to waste some money on shipping I could order a set and have them delivered to Jim Valeco and see what he thinks..


    Doug


    .......wonder if it's a Chinese CNC machine....

    Better idea! Send me the money instead, I will tell you what I think of them.

    Same head:

    I could keep going. But you get the idea. All the same head, from the same supplier. There are probably another 6-8 guys selling on E-bay alone. Boggles the mind about how many sets of these are being moved.

    That's not a pitcure of a BB head, FWIW...and I can just about guarantee Herbert doesn't "manufacture" those.

    for a mild build would the herberts be better than 781's? the shot ones i have need $800-1000 worth of work (large valves, springs, guide plates, etc,etc)
    1200+/- And losing weight?

    It seems as the magic thing with this frick'n POS heads is that they are made of the wonder metal of wonder metals......aluminum. How grand! I would rather buy a set of cast iron Darts or Merlins, or RHS than run a free set of these POS heads. But if you are hell bent to have racey look of aluminum then by all means buy them. It makes no difference whether you get them from doug Herbert, or E-bay, or straight from ProCom Electronincs, they are all the same frick'n POS head. Just remember, the job you cost by buying those heads, may be your own. (or at least hopefully)

    Stay away from Pro Comps and their copies!!!
    My son has a set on his true flat Hondo. It's a pump gas 427 with a small baby flat tappet RV cam and a tunnel ram with a couple 650s. It only runs 90 mph. Thinkin it should run atleast 100. We are sure the Heads are slowing it down a ton so we are going to run a set of 049s and pick up a shit load of power.

    Default Fwiw

    Catching this thread, even though it's a bit older there's a few things to be addressed.

    1) Terry Walters has been in business for 30 years (Check out his website under walterengines in google).

    2) Where we can agree that there have been several problems with Pro Comp parts, if you do your research (again) on the actual ProComp Castings as of late they've improved from where they've been

    3) The difference between these heads, and the ones you but from EBay should be apparent if you look at the specs of the head itself. Notice how the chamber size is 119, not 115, and the flow numbers are different from what ProComp advertises. I actually talked to Terry Walters personally, and after a bit of conversation about an intake, this subject came up. What he's doing is buying the ProComp castings for cheap, and fully re-machining them in his facility. Then, from the exact cam you give him (not just Mech. FT, Hyd. Roller ect), he's using Manley/Comp Cam parts to put your valve train together, and setting spring height for you, based on your exact specs. He'll tell you himself that buying a assembled set of heads from ProComp is a bad idea, because they're filled with a bunch of junk parts, and have obvious alignment issues.

    Personally, I think you're caught between the dilemma of "Foreign Junk", vs a known professional engine builder. Where I probably wouldn't run this in a straight strip engine; a budget street, or street/strip engine wouldn't sound like a bad idea, and according to the flow numbers would work well for a 454-427.

    I don't personally know Terry, or have a set of these heads. But for the work that looks like he puts into them (and posting what seems like legitimate flow numbers that match very close to patriot heads), I'd second guess myself to bash this guy with the rest of ProComp retailers.

    If you have questions, do what I did and actually pick up the phone. Don't expect an old man to enjoy writing e-mails!
