Shoot Martin an email. If you've got cash in hand (little of it for him) I'm sure he can get you one on the way. I had mine 3 days after he mailed it.
You sound like you have a good idea. There is, in fact, a company north of Buenos Aires that apparently has the old casting molds and can reproduce SP cylinder heads for a pretty low price. Unfortunately, like any manufacturer, they only produce when there is a demand. I've always thought that anyone with the funds to order 20 new SP heads would be able to turn quite a profit should they be able to get them into the states.
Unfortunately, this board is comprised of a bunch of money strapped enthusiasts like myself. I would say the average engine build on this forum takes about 2 years from a conceptualized paper plan to a running engine.
I see posts every day from people just "dreaming" about what they would like. I'm guilty myself. As much as I'd love to see a revolution of high tech parts availability for these motors, I'm afraid that's never going to happen. Anyone with a need for speed and surplus funds is going to have a lot of other ideas besides an inline six build. That is, unless they care to make donations to some of the less fortunate hardcore sixers.... 8)

Sorry to burst your bubble but a 302 is always going to be more powerful than a 200. Actually a 289 just comes in over a 200 with a Aussie head.
Look at my dyno results I posted with my Aussie head. I don't think a Argie head will give you much more. Than do a search on my handle and check out the dyno results I posted from my club's dyno day. It show's varies V8's. They are still more powerfull.
Yes, you can build a 200+ hp U.S. 6 cyl. But, why? Just import a Xflow from down under and save yourself some money.
Please don't take this post the wrong way. I love my 6 and would not trade it for anything. But, to honestly compete with a V8 you have to look elsewhere.

TC racers in Argentina are pushing 340HP on 188 motor with a single Weber carb and factory head. That's impressive.

I'm using someone elses computer. So is it possible to get his number. I'll call him internationally. I have a freind who is from Colombia and he is an engineer. I'm sure he can get his point across on any issue I have.

this has been tossed around about a year ago or so. Problems with shipping were supposed to be looked at. Also, it is my understanding from previous contacts, that the problem is not with acquiring the heads, but with the intake manifolds. Currently there is no provision to cast the manifolds.

In small runs, woudln't it be reasonably effective to use aluminum weldments for the intakes? At least for an EFI application. Especially with all the different talk of EFI Oz-2V's, there's got to be some decent designs coming down the pipe from forum members. Water-jet cut the flanges, mandrel bend the runners, weld and go. Warpage would be an issue, but can be designed around. Could make it work for carbs, too with some good design work.
Frankly, I'm more concerned about a good head casting. Aluminum or iron? Part volume, costs, finding a foundry to do them...
If the Forum had molds, we could possibly approach Edelbrock about casting them for us. Their green-sand facility is state of the art (or was 10 years ago).
Just thinking out loud.

Yes. The molds would be great. I'm sure whomever has these heads would like to have American dollars. They go a long ways in that country. I was thinking about trying to get a federal grant to start a performance business. I think some of that money could go to acquiring the molds. Or I could CAD it and have it transferred to a CNC program. Billet aluminum cylinder head anyone? Or at least a prototype. Many designs can be copied. BMW has a great cylinder head. They pull alot power.I think this is an untapped market. What do you think about that Mikey?
Forget Edlebrock. They won't touch anything unless its a minimum run of 3000 pieces and I'm sure it would run well over $250K. I speak from my experience in trying to get them to reproduce their I6 alloy valve covers. Those were the minimums they gave me, and keep in mind, that was for one of their own products.

Richard -I know more about manufacturing processes than I do about design. At that, I could know a whole lot more than I do.
I think a well designed cylinder head is probably easier said than done. I'd have to see a CNC'ed head to figure out things like water passages. Then theres all the design theory behind intake and exhaust runners, combustion chamber, etc. It'd be nice to copy a BMW head with the proper bore spacing and the like for our Sixes, but it's well beyond me to actually pull it off. And billet CNC work would probably price most of us out of the market. There's a ton of time in something like that, and a lot of 4-5 axis work to do it right. Casting would be the way to go in my opinion- but making the cores is probably pretty steep on cash- and the previously mentioned issues on finding a good foundry.
AzCoupe- too bad about the Edelbrock thing. Makes sense for them- they do what makes the most money. Still makes it hard on a small niche market like I-6's.

yes, is really impresive what they can do with a 188, here in argentina we dont have a V8 "tradition", we have a lot of L6 (chevy 194-230-250, ford 170-187-188-221), so we tried to get the best of what we have.
look, a 188 TC falcon, makes 340 hp and max revs at are more than 8000 rpm, they use titanium, aluminium (in some parts), dry oil pan, electromotive ignition, only one caresa or holley 2bbl carb (40/40) with a 6 speed secuencial gearbox but the rules doesnt allow to use aluminium heads, or run engines with 4000 CC, or 3 carb setup, or make heads OHC... but we can run more than 170 mph with a relative "old" engine...
if they were no limits, like 1/4 mile, those engines can easily run 180 mph, and revs close to 10000 with a OHV engine....

Pro Topline has factories in Australia, USA, and Argentina producing new castings of cylinder heads, blocks, entire engines, etc. Unfortunately, they don't offer anything for the Argie or Aussie sixes.
