2 holes on head??

1 hole back passenger side head, 1 hole front driver sides (or flip flop im not looking at the motor) are they both for coolant sensors? Don't I only need one? Should I buy two sensors and just not hook one up? Let me know guys. Thanks!! The motor is only down to a few things trying to get it going!!

There should be two holes in the back of the heads for a metal coolant line to run on each side of the head to the radiator.

If your referring to the once between the spark plugs, not front/back of head. The Drivers side is for the coolant temp gauge, the pass. side is not used and can be plugged.

Head's shouldn't be L/R specific, so if he means the actually flat front, both heads should have holes in the front and back for the steam tubes.

If you mean the hole on the left side of the bottom head, between the first and second exhaust port...

Then that is just for the sensor, driver side. Which, if not plugged, will have coolant leaking out like crazy. Pass. side should be plugged.
