That's not a Super Six air cleaner; looks like a '70-'73 318 item. It's not going to clear any A/C compressor (Chrysler V2, Nippondenso C171, Sanden SD) with a 225. The Super Six air cleaner meant for use with A/C has a flatted front to allow it to barely clear the compressor. It would take a lot more than an extra gasket or two to move the air cleaner up high enough to clear the compressor, then the hood wouldn't close.
There was also an offset-base air cleaner used in some Dodge van applications—that gives even more clearance for an A/C compressor. Beyond that, it's sort of a matter of cobbling up whatever you can.
