I have brought up the idea of having a cast head, I will need a print to fully realize this, so, does anyone have a print of the aaz head sitting on a shelf somewhere?
thanks,
kevin

not sure, however the gentleman asking cannot give me a certainty until I can give him a print of the motor/head, alo used the term blueprint. This leads me to believe that he is perhaps talking about a drawing, as opposed to a CAD 3-d model, or rapid prototyp/3-d printing. I suggested these and he was confused, he didn't want an object, is how he made it sound, more like he was searching for a map, or rather like a hous eblueprint. I have never heard of such a thing, not very surprising, as cast is seldom used in todays manufacturing, and I am only 25 years young. Perhaps some of the veterans or someone from another country on the forum can shed some light upon this. Really why I posted it here, quite puzzling
Thanks,
Kevin

Call and ask for John. This is air cooled engines plus, but he does a ton for audi vw watercooled stuff as well. I would think as many heads as he ported he might have something or at least know where to source something.

He needs a blueprint which gives all the measurements to make a mold for casting.

Yep, and if anyone would have knowledge of the blueprint it would be John.

Not really helpful here, but I wonder if for one off type work you could do this as a sacrificial pattern. That is, use an aluminum head as the pattern for the mold, and then melt the aluminum out of the mold and pour the iron in? My only question would be how to leave a little extra meat on for the machined surfaces. The cam bearing journals could be done the way they used to do some aircraft rod journals, cast it with the top and bottom as one piece, bore and hone the journal, Drill for the cap bolts, and then freeze them with liquid nitrogen and snap them off. This gives a nearly perfect mating surface that will only mate one way, but will not move (at all) once mated and tightened. OT: Come to think of it, I wonder if one could order H beam rods not cut and faced, so that they could be split this way? Sometimes I wish I had a nice little CAM mill, I'd make all kinds of cool stuff.
Anyways, It never hurts to ask, but I really doubt that anyone who has done the work to create a model (or a set of blueprints) for the head is likely to share them. It _shouldn't_ be difficult to break the drawings out from a model, but I suspect that is really a moot point.

I still have a beat up aaz head as a sacrificial lamb, I, however, lack cad and the nec. skills to produce the digital copy. If it exists it is on the internet, I will attempt to use my ninja powers to extrapolate it's whereabouts.
I wanna get the ball rolling on this, not just for me, but for everyone here on the forum. It was suggested to me, "by an acquaintance of mine" by a friend who used to do molds, and whos father is a master moldmaker "lost art :'(" that I should use 43/40 moly I found this unusuual, and as noted in another post of mine I still stick by this as a good idea. any thoughts?
thanks,
Kevin

Myke W the mod on here had a beat up 1.6L hydro head I sold him if that helps. I still can get a foundry to do this up if you get it going.
Is there any way to contact VW engineers and ask them? Just ideas.

I want to use the aaz head because of the feasability and the rarity. As opposed to everyone trying to track down and use an aaz engine, why not just use the aaz head, make more power because of lower static compression and the head just breathes better. Not only that but users of the aaz head would be able to go hydro or mech. I was also making a prediction of demand assigned units, that is, I figured more folks would want an aaz head anyways. In the future, provided I can find a way to get the cost down etc. I planned to have all of the variants made from a stronger material than AL. Price per unit is definately an issue here, the majority of folks here don't want to spend a fortune fixing their cars up so demand and total units produced will def. depend on price, which is opposite to how it works most of the time. I would love to know if VW would be down for bringing bach the old IDI in a "new" look.

I meant asking VW for the blueprints. I understand what you are doing I am just trying to help make it all happen.
