What Overhead is this?

Post by Rich Eagle » Tue Jun 27, 2023 1:44 pm

I can't seem to find the make or model of this overhead setup. Most rockers are on shared shafts rather than separate standoffs.

I don't see a outlet to the radfiator either.

Curious.

That’s interesting. It looks familiar but I can’t place where I’ve seen one before. It has subtle similarities to Rajo but it’s not. I believe the water outlet is in the center where the rag is stuffed, and a pipe/water manifold led to the radiator inlet. Hmmm

Might be a HAL conversion without the rocker cover.

The only HAL heads for a T that I know of are the earlier production “run in oil”, and the Akron-Hed. Definitely not either of these.

These same pics surfaced a while back… and as I recall did not get identified. I was just cruising the Speedway museum a couple days ago, and did not see anything with exhaust ports like this one. It’s a neat design, sure would like to see more of it!

It looks like the head is mounted backwards! The red arrow is pointing to what looks like the water outlet flange.

Thanks, I will try to get some more pictures of it.

No, it can't really be on backwards; the cam is on the right, the rockers have to stay there, too.

There is quite a few oddball OHV heads out there, whose makers are lost to time. They are often not crude in their design, and very few were made, if not one-off. Another mystery.

Thanks for the speculation. I am trying to decide if I need another project. It's in a car that doesn't attract me but might be worth it for the head and some of the parts. I need to go and see it. If not, I'll pass the information on in case someone else is interested.

I answered the question of "where does the water exit the head". It is in the top and center and was obscured by a rag in other photos.

I can see no markings or name to who made this head. It may be early with the somewhat crude rockers and standoffs. The push rod adjustments seem like an earlier idea too.
Anyone else have any thoughts or information?
Or have I stumped the band? :lol:

Looks a lot like an early Liberty Head.., They were used on boats for the most part. Thats why there is a center return on the water outlet. Not very efficient for a car with a radiator since early boats used a forced scoop system.

I thought the exhaust ports looked a lot like a Robert Roof head I saw a long time ago, but I wasn’t sure. Robert Roof also used the name Liberty , so that would be another name for the same thing. With the stock T water inlet location in the block and having the water outlet in the top of the head , it could be problematic in getting good cooling in the rear of the head if used in a car. In a boat engine that cooling would not be problematic because of the constant cold water intake and no radiator.

I am sure it could be made to cool ok in a car with some sort of baffle and maybe a water pump.

FWIW, REO used similar rocker arm mounts with the yoke and threaded into the head for several years. Rollers on the rockers is interesting.

Yeah, I would put money on it being a marine accessory head. There’s many an obscure accessory head sold in catalogues back in the day, we tend to only recognize the major successful manufacturers though.

Rockers appear to be on individual stands and separate, not shared.

I’d like to add, this is the fascinating part of the hobby, when an unusual or long forgotten accessory shows up. It fun trying to identify a real head scratcher.

Searching for the odd stuff is fun. I often get sidetracked on other odd stuff I wouldn't see otherwise. This head is fascinating.
I hope we find out what it is.
