Have you owned this Lancer since 2002 w/o a spark plug change? Hope not...

 

Don't be afraid of doing it. The spark plug work will lead you towards the turbo install. It's only a matter of jumping in.

 

It's unlikely that your head gasket is causing an ignition failure. For some reason the wasted spark system on the Lancers and Evolutions loves to misfire and throw codes. Go fig. If the plugs are relatively new I wouldn't even bother changing them. I'd just check to make sure they're clean and properly connected, reset the ECU and be on my way.

If your head gasket failed you'd see carbon buildup between the head and the block, and the loss of compression would probably cause the car to run horribly, if at all. Taking off the head is a lot more difficult (though still not terribly difficult) than checking the plugs...so unless you start throwing all sorts of wacky codes, just stick with what the scan tool is telling you and go one step at a time.
