There are several marine intakes, both for the Rochester 2G-type 2-barrel and the Q-jet spreadbore and Carter squarebore (uses an adaptor) 4-barrel carbs, all cast iron. In fact the only aluminum intake for the V6 Chevy 90º is a 2-barrel single plane(!) piece that was used for several years on the 200 and 229 cid engines. Not a performance-oriented part, it has a bolt pattern for the Dualjet (basically the front half of a Q-jet), which means no other carbs will fit it and there are no adaptors, either.
