Good info felixthecat. Thank you.
I'm going to move forward with the job.
The two cars are not currently available for a side by side comparison.
What would happen if I did a straight swap without changing the head as suggested?
Would it be easier/cheaper to switch the pcm out rather than putting the 2.3 manifold on the 2.0? I have the entire 2006 2.0 at my disposal. The damage didn't affect the engine at all.
