Scored Offy dual quad intake for my 392 WEDGE project!

I've been thinking of doing the dual quad thing to my 70 340 with 202 U heads . I cant seem to find any intakes that match up, only the ones for 273 and 318 poly. I looked at all the main players including Offy and found nothing. Just looking for the "cool" factor and not really any performance gains.
Thanks, Jerry
