oil filter/ex manifold interference Q

I mocked up the manifold/flat plate/nipple & the filter on a seperate engine cuz I wanted to go that route if I could for the simplicity & that's when I got the 1/4" clearance. I do have the 90 deg adapter/bolt & the 3 piece gasket set but I'd like to go with the plate/nipple. EDIT the filter was a long one
