2009 Base 2.4L Head Gasket - Must remove Engine/Transaxle?

[daneaparker]

I'm hoping to replace the 2009 Vibe 2.4L head gasket without removing the engine/transaxle (5-speed auto) from the car.

What other maintenance should I do at the same time? O2 sensors? New valves/springs/seats/other? Plane the head?

If I have to remove the engine/transaxle, what additional maintenance should I do? Motor/transaxle mounts? CV joints? Trans rebuild?

Any input would be greatly appreciated!
