I just received a indy 401-1 single plane intake for my 401 and I have a couple of questions on the it. At each corner of the intake it has a threaded hole for access to the water passages. The front 2 are in the crossover with the thermostat housing and i intend on plugging these. The rear 2 do not have a water crossover between them....my question is if these 2 water passage ports should be connected to each other or to the front ports for water flow through the heads? Or can they simply be plugged? Which have you done or what do you suggest? I plan on contacting Indy to ask the same question but it's kinda late right now. Let me know what you think! Thanks!
