Here is a breakdown of intake height applications for big block engines, cast iron or aluminum:

65-69 Chevelle & Impala, all engines, high rise
67-69 Camaro, all engines, high rise
65-67 Corvette, all engines, high rise
68-69 Corvette, L88 & ZL1 applications only, high rise
68-75 Corvette, all except L88 & ZL1, low rise
70-75 Camaro, Chevelle, and Impala, all engines, low rise

The low rise intake first came into production with the 68 Corvette and was due to the low hood lines of the big block hood. Then in 1970 all big block applications received the low rise intake no matter what car it was installed in. The Chevelle could have still used the 69 style high rise intake as there was plenty of hood clearance but to keep costs down Chevrolet stuck with the one style of intake. That is why the Chevelle with cowl induction uses a spacer between the air cleaner and carburetor, so the rubber seal will set against the bottom of the hood...................RatPack.................... .
