Here's my Flathead six Chrysler. This one is the industrial 230 ci. with the short 23 1/2" head. I think the different lengths of the head just mean that Chrysler didn't have to Siamese as many cylinders not that they necessarily made larger cylinders, on the longer ones. There were some bigger displacement ones though. I'm supposed to run it at 1500 revs at high idle in this 1954 Massey-Harris 33 tractor.
