Yet another hood clearance question

I have a 71 Twister with a built 440. The Twisters didn't come with the fresh air opening under scoops..well I installed them last weekend now my hood will not close because the hood donut hits the snorkel on the passenger side.
I love the look of the air cleaner and my question is...has anyone bought a drop base air cleaner and used it on a dual snorkel...I know the bottom would have to be cut out and the drop base tacked on...I just don't want to ruin a good air cleaner if it won't work.
Not sure if an unsilenced one is the same.
Any help would be great..thanks
