Aluminum High Compression Low Head Details

Looking for any details about any of the the aluminum high-compression low heads that have been on the market place over the last 50 or so years. Details and photos of these heads are hard to find, other than it has been reported that the most recents ones manufactured are said to have a 6.0:1 compression ratio.

I'm looking for photos of the combustion chambers of any one of these heads which have been manufactured recently.

Here’s a recent discussion bout the Reeder and similar heads;

Here is a comprehensive comparison of several heads done in 2011 I believe http://mtfctulsa.com/Tech/heads.htm
You'll need to navigate through several pages to see it all

Thanks for the links, I appreciate it.

After pondering how to build a new Winfield head for several years, a little inspiration and curiosity yields something very similar to a Green. Better pics, or better yet measurements, and a little more patience could get a design that’s really close to an original...

Very nice work! Have you ever gotten involved with casting something like this? After having recast and machined several pre-WW1 engine blocks recently, the old-fashioned way with wooden patterns - modern cad design and core printing is the way I would do it from now on.

Have you even been involved with a casting with printed cores? Any chance you might may do a Winfield head? I've been thinking of talking with friend Lee Stohr at https://www.stohrdesign.com/ about doing a Green head if I decide to go down that road.

Have done a couple complete 3D printed sand molds. Here is my dual Winfield manifold project

Perhaps another option would be an original, never used Winfield head from the day the racer was shaking up the racing world?
It is interesting that Winfield never cast a water inlet in his head. He used two inlets on top of the head with a manifold arrangement
similar to an exhaust header to transfer coolant. I expect it reduced the water capacity in the head, but provided more equal cooling.

Has the head design of the Hudson flat head six cylinder head from the early 1950's been studied. These cars were beating the rocket 88 Oldsmobiles in the stock car races. In the late 1980's I worked with the engineer who had worked on this Hudson engine. I wasn't smart enough to ask him about details. He passed away in 1993.

Kevin,
I am in Panama right now so don't have ready access to get you pictures.
I purchased it a quite a number of years ago from another collector.
When I get home next month I will get you some pictures.

Some ideas presented here could be of interest? I hope it can be watched

As close as I’ve ever been to a real Winfield...

Nice work, this is the way to do it today if you can. Saves a lot of work and the end product is superior to doing it the old fashioned way.

Not T related, but below is the most complex casting I've done to date. A new cast iron cylinder block for this 1915 Duesenberg racing car 300 CI OHV 16-valve four. More info and photos @ https://theoldmotor.com/?p=157435 and https://theoldmotor.com/?p=20330
