Gene and Hugh,
I realize the 140 was built for 20 yrs and I may not know about latter changes, but at least the early 140 motors that I worked with do still have the 9 bolt heads. The water pump arangement is different but that change is on the front of the block, not the head. ie: the 140 and Super A block is not interchangeable without changing the pump and all the accessories on the front end, but the head should interchange fine.

It will bump his power up as it is a smaller combustion chamber and bigger valves. It also has a different manifold and larger carb that won't line up with his original air cleaner. To keep it looking stock, use your original manifold/carb/air cleaner, but do a little port matching on the manifold to head. Otherwise I think you could swap in all 3 parts from the 140 as well for a better power improvement. This is conjecture, but only caution I can think of is if it has a factory firecrator S&P set that expects the larger combustion chamber it might interfere with the head, but I doubt it.
