I am sorry to say I traded the intake for an intake with a member here. Looking at your picture, the threaded hole on the right I didn’t touch. Where the temp sender is, I drilled and tapped. I know this is accurate since I do not have a tap for the heater hose.
Must have come from the factory that way, heater hose already sized at that position like you say. I was confused because mine came differently (like 93ragtop's).
