Another thing to do is change the thermostat, read of one instance where the owner thinks a faulty thermostat caused his head to overheat and crack, being the not so proud owner of a cracked head I wish I had been more vigilant on that incase it had a bearing on mine.
I'm a member of the cracked head club as well, but nothing to do with the thermostat. Brokenn exhaust roller bearing that then lodged UNDER the cam (the cam then proceeded to try and push it through the head) did mine. Luckily the local "head job" guy managed to weld it up. 10,000 kms and all good so far.
