If a fella couldn’t read… he would say that thing looks exactly like a Green Engineering flathead…!

Re: Looking for info on this head
Here's photo of the Green head.
The one by OP has metic spark thread holes, they aren't std Ford USPipe thread.
And Interesting round disc lump on top rear of the head and casting spots between cylinder for maybe drilling to add petcocks.

Courtesy of Google books - the only references I could find searching "turbo centaur marine" were in 1926 issues of "Power Boating".

I also found this add early this morning but didn't have time to post it then. After enlarging and editing it I see a Schebler air valve carburetor, an oil pump and lines, and a side-drive attachment for the ignition distributor.

Has anyone ever ran a green engineering head ? I would like to hear what their thoughts are. John
Who's still makes these gaskets, I might be in the market for a solid copper one myself.

Re: Looking for info on this head
Wonder if the round bosses on it were to be drilled and tapped for a water manifold with the original one blocked off.
I know the voices aren't real but damn they have some good ideas!

Re: Looking for info on this head
This head is really intriguing! Since it states in the casting that it is "marine", I cannot help but wonder how the heads higher compression might affect performance. Most engine powered boats in those days were not high speed. Maybe the squish and flow area of the combustion dome was set for lower speed torque?
Regardless, if it were mine? I would want to put it on a known good running car and try it out to see how it would compare.
Another consideration of marine heads? Often they did not use a radiator mounted in the normal front location. Sometimes, they didn't use a radiator at all! Boats often ran water from the lake, river, or ocean water they sat in to keep the engine cool. Years ago, I saw a marine head that mounted onto a model T block with the radiator connection at the back of the engine. This one at least looks like it could be used on a model T car? I also feel that the large round embossment may have been for adding additional water routes if needed.
Interesting piece for sure!

Re: Looking for info on this head
Take a volume reading of the combustion chamber. (CC's) & figure the compression ratio.
Notice it takes special, flat top pistons.

Re: Looking for info on this head
That head does not look at all like a Green head. The Green head did not have a squish style combustion chamber, see https://mtfctulsa.com/Tech/head_photos.htm. We attempted to run one on a dyno 20 years ago. The contour of the chamber caused the valves to get wedged with only a 280 cam. You would have to relieve that area to run one.
