Interesting collection of blocks from the era. Just one Model T block - the one in the foreground.
Isn't the block standing on its end on the workbenc behind the vise also a T block?
The block with only 1 valve per cyl looks interesting. Hudson F head maybe??
They all appear to have been freshly bored and some of them make the poor old T blocks look like midgets.

Henry, it doesn't have nearly as much radius around the water jacket at the upper end of the block (in the picture) as a T. Dave
The block with only 1 valve per cylinder is a 4cyl. F-head Hudson Essex block .
How did that work? I am unfamiliar with the F head.
Also, the one on the table looks like it has valve guides inserted, ala non Ford.
The block on the table does not have the large center water jacket hole between cylinders two and three. Not T.
Erich, a F head or IOE (inlet over exhaust) engine has one valve in the block and one valve in the head per cylinder. Examples most HD 1903-29, Jeep 1950-1971 etc http://en.wikipedia.org/wiki/IOE_engine
That boring bar on the right looks an awful lot like the Storm unit my brother and I first picked up when getting into the hobby 30 years ago.
Another F head was REO from mid-teens till about '26. And T related, the Rajo model A (four valve) is technically an F head.
Great photo! (I need that T block.)
Drive carefully, and enjoy, W2
How are the valves operated on the model A F head?
This picture plainly shows how far we've come.
The technology from heavy cast iron blocks to one piece aluminum engines. "Great Photo" Love to see old machines.
KEP,
The F head retains the traditional flat head exhaust valve, as-is. The intake is now an overhead valve, located in the head, actuated by a rocker arm & push-rod.
Kep, The push rods on Model T and Model A accessory heads goes through the former valve guide up through the accessory head. The new head gasket seals off the former valve seats in the block.
