At first I thought it was an unfinished or incomplete OHV now I realise it is a two piece flathead. Interesting. I would also like to see more photos.

 

This looks very interesting, show me more.

So I have a friend that has a machine shop and right now he has two new model a heads that he has been asked to cut just like this so they can check the casting quality.. you guys think this could be the same thing. Could it originally been all one piece?

Well now that I think about it they wouldn't of threaded the the sides of the spark plug holes

Here is another picture with a Model B head gasket.

 

No this was just a very easy way to cast the water jackets in a aftermarket head.

Have you checked the compression and what are your plans?

 

If you need to test it out I would be happy to try it out for you on the old 73b

I have not checked the compression. I would like to run it but it needs an auxiliary water pump and I have to find or have an inlet pipe made. Also, there is no way to mount a fan and I will not use an electric one.

I'm told is is part of R&R's Blue Streak collection.

 

What about a T aftermarket pump, push the water instead of pulling. Plumb the two top outlets together and you might not need a fan.
