I picked up this head a few years ago. It is a 2 piece aluminum casting. Anyone know who made it?
I hope Bob Scherzer sees this.
Now that is a neat head!!! Thanks for sharing it with us!
It is neat. You would really have to trust the Permatex with that one....
sweet!!! what does the chamber look like?
Scott, With no pressure in the radiator it should seal up ok. Just my think, Scott
It could use some guide tubes around the bolt holes, between the sections.
The flip side. Other than plug location combustion chamber looks much like Ed Winfield's T head.
Of course you are right scott. Something else to look for. You have to wonder how many of these are out there??? Does the name really mean Go-T
When visiting in California a few years mack I went to a high end car show in Morgan Hill, after i visited a T person there and he showed some just like your head, If I remember right he said that he and his father was making them. I just look and found there card. This was 10 years ago and I don't know there status now.

The "goatee" head looks like the same shape as the head Jerry Hoffman bought in an ebay auction 2008, see this thread: http://www.mtfca.com/discus/messages/50893/70987.html
I posted a question about the head to the seller. He responded:
"This was made by a friends father about 10 years ago. What I was told is that he made about 15 heads and he used one on his Speedster and had no problems. I got one for my speedster but never put it on then sold the car. I realy don't know any more info on it. It has never been on any car.
Great method to simplify the casting process for low volume head production
here is my question... how would this perform against a z head and how much would it be to have one cast?
The Z head has a Ricardo configuration. No cores are required. If I were to make one of these I would copy the Z head combustion chamber. The combustion chamber on the Goatee head doesn't look well engineered to me.
The compression ratio might be higher than a Z or Prus head, while the general shape of the compression chamber is less efficient (no squish area over the piston) so it's hard to tell without testing like the Tulsa guys has done: http://mtfctulsa.com/Tech/heads.htm
Having a one off head made in this fashion would be possible by milling alone, Brent in 10-uh-see told us about Norm Frick from Colorado making such heads for $125 per cylinder = $500 for a 4 cylinder head back in the 2008 thread.
Nice design but they both look like they're missing some steam ports.
As Ted Dumas says, No need for cores with that design. And, As Roger Karlsson says a better combustion chamber design would make it a real winner. Our son Steve had an Edelbrock intake manifold set-up for a four barrel carburetor on his Capri V6 Coupe back in the 70's. The manifold was cast in two pieces much like that head and you could select different tops to run different intakes with the same base mounted to the valve galley.
He had headers and it was a going concern. The idea of a two piece manifold or cylinder head is not a new idea by any means and if Edelbrock did it ,it must be good and work well.
Ken, Maybe The manufacturer thought if you used a water pump, the engine wouldn'y get hot enough to steam. (grin)
Could you flip it and shape the combustion chamber more with the piston, a la our V8 younger bros?
Make it a taller slug but then dish the piston towards the valves and plug?
Ideal to make from plate on CNC machining center. No trips to the foundry, no pattern making.
The person that made them said that the water capacity in the head was greater than the stock head for better cooling.
A CNC head would be easy to fabricate if it's a two piece design. Not a head but here's a throttle body I machined from billet a few years back. Typically these are castings.
Does that mean that at some time in the future, we could see something akin to a hemi head for high compression pistons in our T's, that would compress exactly to where it should ??
Yes and no David - yes in that it is very possible and doable, no in that it really wouldn't help you. Unless you are talking about a Rajo head - more important than compression in these engines is the flow in and out of the combustion chamber. A dome pressing into a curve doesn't help the burn or air flow.
What you might see that would be really cool is someone doing something nifty with the general shape and design of the Z head. Maybe instead of one fat wedge in the middle you would see two smaller ones directed at the valves - I don't know, just made that up as an example. I'm sure someone could figure out a way to make a head for domed pistons that gave you 7:1 compression, it just wouldn't matter cause a T with a Z head would still blow by them: that 7:1 head wouldn't flow very well at all.
If made on a CNC, could it be made from mild steel?
At the Hutchinson, KS Winter Clinic two (?) years ago, there was a great presentation by some folks who are doing just what Philip mentioned. They have designed a completely new OHV head for T's, and are CNC-maching them in two pieces like the Goatee one shown above. I thought we would have heard more from them by now. Does anyone have an update?
CNC could be used on steel. I suspect aluminum would be easier to machine.

I have found the maker and will get as much info.as I can and post it here as soon as we complete our phone tag.
Could also be made from slabs of DURABAR G2 if you want it to be cast iron.
Phone contact with David tonight. The designer
along with the caster are no longer with us, He acquired the parts and sold some, Only about 15 were made. They are 6 to 1 compression and holds 2 qts more water. He still runs one along with about 6 being run in different cars in California
at present. He knows of no complaints on them.Hope this helps. At this time there could have been a better design but for then it worked very well.
PS Can Not be used with DOME pistons.
There's no need for CNC machining these days. You could print a new head with an additive-layer 3D printer in your choice of several metals.
Change the cam for one that opens the inlet at the same time as the exhaust and add a head with vacuum inlets.
Interesting head Mike. Apparently the builder(s) wanted to avoid the whole core issue. Could be done by CNC if you wanted a one-off chamber shape.
