I am quite sure this is the case. I have a Canadian GMC 216 with short side cover.
It seems to me that I ordered a gasket kit for a Chevy 216 from the states, and found that the head gasket did not work. I had to buy a different head gasket and specifically request a 235 gasket instead.
Also, if I am not mistaken the exhaust ports are also bigger on the 235 head. I found this out when I swapped engines with a '51 passenger car 216 (tall side cover) and tried to install the original truck manifold. The ports in the car 216 were smaller, hence this leads me to believe that cars used a 216 head and trucks used a 235 head.
