Can a 2000 1.8 head be swapped for a 2003 1.9 head?

(guessing that a 2000 S40 turbo US version is a 1.8 or 2.0 engine?????)

The head on my 03 V40 is warped thanks to a mega overheat, and I have access to a 2000 engine.
Thanks

 

The North American 2000-2004 version is the 1.9L engine so I think you should be good. The head bolts are torque-to-yield so need to be replaced too.

 

Thanks
Ordered parts and started teardown..
