I measured both my H/W single setup and my C/W dual setup. I'm running a stock manifold on the H/W and an Offy on the dual c/w's.

From the bottom of the adaptor plate to the top of the carb (where the air cleaner makes contact on the bottom) it measures 5-3/8". With a 2-1/2" paper filter and spun aluminum cover the overall to the top of the wingnut measures 9". This was the same for both H/W and C/W's.

I'm not sure if there is a 1" paper filter but using a flat plate on top might give you the clearance.

I've got some pics of both the H/W and C/W's in my webshots albums...you might be able to get a better idea from them. Hope this helps.
