The UB220 is the industrial version of the BD-220 six used in the trucks from the early '50's. Yes, the C-221 is derived from the same BASIC design.
That said, the BD [Black Diamond] engines came in a straight-valve configuration [early engines], and a tilt-valve [later engines]. The tilt valve has a wider valve cover. On the truck engines, if you put the pistons from a tilt-valve engine into an engine with a straight-valve head, you end up with around 13:1 compression...and usually major overheating, until you figure out what you did.
"Better" is a relative term. IH went to the tilt-valve engine because the straight-valve engines developed a reputation for hanging exhaust valves open, after which the piston would lop the head off the exhaust valve, with a bit of noise and a distinct loss of power. Tilt-valve engines weren't known for having this problem.
Others may know better about the bellhousing patterns. I'd wager they'd be pretty close...but I've been wrong before.
