I have a cylinder head I removed from a '23 engine a while back - don't have the car anymore, so don't have the serial #. Wondering who, when, why was it cast without the beloved Ford script on top? Love that big "Ford" script bling looking at you when you open the hood! Any ideas??

Other records indicate that in August 1926 the " Made in USA" and "Ford" were being eliminated from the head castings.

Dan,
Thanks for the reply. It pays to work with the experts!

Well. have owned a couple of '26-'27s, and found out the later motors came with the 'bare' cylinder head!





And if you are placing a new high compression head, like the good Prus head, on a late '26, those are un-marked to keep cost down by no trademark selling price percentage fee to FOMOCO. So looks class judging authentic, but with more zoom

Prus high compression head

A coincedence you mention the Z head. I have a '27 Speedster (has a Ford script head - someone must have changed it before I got the car) and have actually been thinking about installing one, but have all but talked myself out of it since I'm not sure how robust the bottom end is and sure don't want to hazzard breaking a crank.

If your rods and main babbitt is good, meaning no rattles or thumps now, shims left, and you have been running fine, adding a high compression head won't hurt anything in the bottom end.

Breaking a crank is a hazard anyway, with old cranks that are about 100 years old now. Don't think a high compression head is an independent circumstance of a broken crank.

While I haven't placed one on a used engine, only on fresh rebuilds, IMO, there isn't that much issue for a good condition motor.

I have a low head with no FORD or made in USA, was told it was early Canadian? Might be interested in finding it a new home.

Steel or aluminium, Joe ???

Cast iron.

Dan,
I have no idea about the true condition of my engine since I traded another Model T for it a couple of years ago. When first got the car, I noticed a very slight little knock - in my estimation not enough to be concerned about, so I removed all the shims from the rod caps and installed dippers while I was there for insurance. It sounds better, but not completely gone. It starts and runs very well and provides free starts regularly. Since it's a speedster, it's very light (no body, fenders, splash aprons, or running boards) and I've clocked 50 mph without the benefit of any auxilliary gearing. Taking all that into account, would you still recommend installing a Z head? Besides increased speed and more power for climbing hills, are there any other benefits of running one?
