Ford didn't introduce their first engine with valves in the head until 1951 with the 239 Y block engine. Before that, they were all L Head designs (affectionately called Flatheads). Valves in the block = fewer moving parts.
The one BAD thing about a V8 Flathead is that the Exhaust passages go through the water jacket to reach the outside of the block. This one little design "feature" makes it warm up really fast in the winter but also leads to easy overheating in the summer and many cracked blocks.
