Hey man, thats what I run into with my intake. All these holes and nothing to put in them. On your intake, Holes A, B, and D can be used for a water temp guage. Hole C is for and air/ fuel Mixture ratio meter. After I decided which I was using for the water temp guage, I went to the local hardware store and bought some plugs. Works Fine.

A) For heater core return (supply would come directly off the water pump).
B) Best place for water temp sensor.
C) Either air charge temperature sensor, vacuum guage, or as a supply for your vacuum tree. This is the only place to draw manifold vacuum. Don't see how you could do air/fuel ratio monitoring since the mixture hasn't been burned yet.
D) Plug it. Don't take your water temp reading here because it will read quite a bit from the front port.

D most likely can be plugged. Ford uses that port for a temperature switch for some emissions stuff.

alright, sounds like everything is agreed upon, as for the heater return hose one, what is that used for? how do i hook that up? im sorry if these are rediculous questions but this is my first time rebuildingn an engine, and it came with none of these on the stock manifold.
