you know i was looking at this recently and wondered about people who just go DOHC and no turbo or plans for turbo. Why dont you just get a Stock GS water pipe, thermostat housing and top outlet as the bottom outlet is still the same part as the SOHC and run stock GS radiator hoses, that way, no dual radiator cap setup or extra lines to block off and no weird fitment as they use the same radiator.
parts you would need
Water pipe- MD189194
T-stat housing- MD188386
Water outlet- MD190840
Upper rad hose- MB845903
Lower rad hose- MB845904
also, for pre 97 cam shafts, there is still the slot for the Cam angle sensor so do not try to run the interface plate way as it is a headache, just use a 1G CAS or 97-99 CAS
