Thanks guys and I didn't sleep with them. I dropped them off at the foundry today and have to talk with the owner tomorrow to finalize the cost for the samples. The guy I talked to thinks it's going to be about two weeks as they need to install the runners and vents on the form before being able to poor. The owners son is a car guy and he thought that it looked good.
The sample run will consist of two manifolds so they can be machined and then test fit onto the truck. That's the part that kind of scares me. A lot of work, time and cash all culminating at that point.
Thanks Alex. It means a lot to me that some of you have that kind of confidence in my engineering skills.
I've been thinking about a production run and I'd want to be able to stock some spares in the event that there is a problem. I would hate for someone to experience a crack if nothing more than a defect in pouring that one piece and be without a readily available replacement.
I need to think more about this and for anyone interested you should put some time into it as well. That way we could come to some kind of consensus and understand the risks involved.

Rick what beautiful ..piece of art, marvelous. But Rick don't forget the manifold need to be tested day or so after day in 1500 degree plus temperatures without cracking, warping or simply melting away.
If so, is the highlighted part the one that you speak of? (17882)
And if that's a yes, do you also need the clamps right above and/or below it? (17882A)
well MOT this goes to show you how my memory is failing. I don't remember the elbow in that piece and it looks like it reduces from inlet to outlet so it matches the Turbo. Thanks for posting it up. I was hoping to put that bellows section in to hep deal with engine torque but it doesn't look to to be a solution now.

It's being poured out of ductile iron which is thought to be one of the better choices for corrosion resistance and stability. But like you said, you just have to run it and see how it performs.
You probably know this, but just in case... A ductile iron with high silicon and possibly moly is best for the heat. The stock 1FZ manifolds are actually cast from this stuff, which is normally reserved turbo type applications.... again showing the robustness and durability built into a Land Cruiser.

The clamp on each side of the bellows has the same part number, so maybe no reduction there. Mot would have to take a look at the part to be sure; it's too tough to tell from the diagram.
