Has anyone else had to have the entire head replaced? I smell recall.

[crop000]

2006 H3 bought in Shreveport Aug 05. Turn over 55000 in Dec 08. I had a check engine light come on ,onstar said emissions, never ran bad. Took it to dealer, they replaced the head, it was out of waranty but they covered all cost plus four day loaner car (09 CTS). They said #2 cyl had leaking valve.
Seems to run alot better, feels like a few more horsepower, noticed this traveling down i-20 going up hills.
