Actually I doubt that an A12 aircleaner will ever fit under any factory hood with the weiand intake no matter how short the throttle bodies are. The A12 base is the tallest of all the available air cleaners. It Is not dropped like all the rest. I have my doubts about fitting any kind of factory style air cleaner under your factory hood. Might not even fit with no air cleaner. Close the hood slowly. I have one of these intakes sitting on a shelf. Only place it will fit with a factory aircleaner.

Please keep in mind that the Weiand intake was designed over 45 years ago to run NHRA SuperStock F or G in a fiberglass hood car with no aircleaner. They did not care if it fit anything else. Paul Rossi said there was no reason to rev past 6500 rpm and that was with a stock stroke 440 and a .750 lift roller cam. Now days they use sheet metal intakes and rev 2000 rpm higher.

Since you want to keep your stock airgrabber hood, I think you would be better off to just put TF 240 heads on it with a Hughes modified Edelbrock Intake. Just sell that Weiand intake for a bundle. The only Six-pack intake that would flow enough for maxwedge size ports on a stroker engine is a sheet metal tunnelram or the big Indy tub and they aren't going to fit your hood either.

I suppose I should add that your airgrabber scoop is probably the smallest fresh air scoop Chrysler ever used and will likely restrict your engine somewhat no matter what heads or intake you decide on.
