Ron,
I respectfully disagree. My rather involved visual comparison of the 140 hp 
head air passages compared to a 110 hp head found that the openings were 
virtually identical.
Also Chevrolet engine test reports show very similar temperatures for 140 and 
110 engines under identical test conditions.
