Even though the car is only four years old it does have 160K on the clock so a general clean up was required anyhow. There was alot of carbon build-up around the rim of the cylinders.
The gasket didn't actually blow, it just developed a leak and started running like a dog (coughing and hard to start when warm). The thermostat has been removed, but so has the head ATM.

carbon build up is normal on most cars around that mark, just hope you did'nt remove the carbon when you replaced the gasket. If you have developed a leak, as you say, I would be interested to know what the rear welch plug in the head was, ie brass or steel. as for head bolts stretching, I've 2 thoughts on that matter, which I wont go into on this page. let me know about the welch plug.
