John, it looks like a low head. with Frank's experience, and that of many long time T owners, things get to have familiar proportions. You can double check his opinion by taking out one spark plug. Bend a piece of wire into a U shape about 3/8" wide at the bottom and put it through the plug hole. you should be able to feel a ridge around the bottom of the plug hole. High heads do not have this ridge.

Hope this helps.

Another fast way to tell is viewing the bolt ends holding the upper radiator outlet casting.

On a low head all the threads of those bolts can been seen protruding.

A high head masks the lower portion of those exposed bolt ends.

Would be very noticable on your low head, except the bolts aren’t stock Ford fasteners but are modern short ones. ;)
