Those would be a No Brainer for me. Deep port the flanges of the performer intake to match a set of 1243 Fel-Pro gaskets (theyr'e a performance intake gasket for a 273/318, but they match a J head's intake ports well), and install the cam on a 105 ICL. The compression boost and low lift flow with 2.02 J heads would work pretty well. It would certainly work some better with the high gears and somewhat tight stall.
