A: - That goes to the heater core.

B: That is the rear knock sensor

C: This is left empty

D: This is the front Knock sensor

Blue Circle: This are for both of the water sensors. Beware - The single plug sensor is usually the wrong thread. You can either cross thread it in or re-tap it.

Green Circle: If you plan on removing the water to oil cooler, use this to put the oil temp sender in. If you keep it, there should be a bung in here.

thanks for the help, found out that due to using a haltec computer and not having a heater i will have to block off all the holes on the intake side of the block.
