dual quad low profile?

Bummer. The Offenhauser 2X4 low rise & hi rise both state emphatically that Holley carbs will not fit; even sideways; and the only carb combo I've even considered is a 2X4 Holley setup with vacuum secondaries. :cwm10:
Also, they're both set up for square-bore carbs, so Holley is about the only way to go. I dislike adapter plates with a passion. I'll have to do more thinking unless somebody else has a better idea.
