Ok so I have the hooker super comp long tube headers with an ORY pipe. The problem the headers have no O2 bungs. I need to run two O2 sensors (1 on each header) question is where do I need drill the holes for the O2 bongs? Do I drill the holes at the 1 and 2 down tubes on the headers or at the collector. Keeping in mind there is a 396 lt1 motor that these headers are going onto.
