So in my haste I put the right side headgasket on the drivers side and the left on the passenger side. Since they are both switch will the coolant flow be ok just reverse of what is ideal? Should I see what happens or pull it apart, the motor is installed but harness and fuel is not hooked up. Its a 2001 V6.

 

I'd swap it. Some holes are blocked shut for a reason. Don't want coolant going where it shouldn't. Thats just a common sense/better safe than sorry, guess though, I'm not a mechanic.

 

Well they are blocked to direct the flow of coolant. So if one side was switched and the other was not the coolant would flow only on one side of the heads. But since they both are switch I believe the coolant will flow throughout but just reverse direction of what is designed. Since the motor is in the car its probably 6hrs of labor and 100$ in head gaskets to redo. Just need someone to confirm my theory.

 

Bump... All the gear heads here, someone has to know damnit lol.

 

lol yeah I thought for sure someone would have chimed in by now. Well if no one does I'll post the results once I fire it up. I guess then we'll have an answer.; )
