You didn't mention the 376's, is that because compression is too high on aerc flathead?

As Drolston mentioned, those numbers are referring to the amount of can lift the heads will take. Meaning, 400 will accept a .400" lift cam, 425 will accept a .425" lift cam.
So if you have the stock cam in there, 375's would also work. If you plan to change to the cam to a different grind, you'll just need to be mindful of that.
