oil filter/ex manifold interference Q

63 dart stock car 360 with magnum ex manifolds. mocking up on the pass side useing the threaded center nipple/flat plate then the filter, at one point the ex manifold outlet flange is 1/4" away from the filter body. will this overheat the oil? I could use the 90 adapter if need be but I'd like to stay with the other setup if I can. (its congested down there). what do you guys think? & thank you for your time.
