<i>Ensure that when changing the cylinder head or head gasket each liner has the correct standoff as otherwise you will have wasted your time and the head gasket will still blow (note this is very important but lots of people still do it everytime).

[i]It's important to note that head softening isn't the only cause of gasket leakage, correct liner heights are essential to gasket longevity, the liners should stand 2-5thou proud of the block with the engine cold, if they are less than this then the gasket can leak past the fire rings when the engine is hot, more than this and the rubber coolant sealing ring can give up the ghost.
Make sure you check this when/if your head is off, there is a partial fix for low liners involving a modified Rover type gasket, but generally speaking if you have low liners you are overdue for a gasket failure, the real rub is that it is impossible to tell until the head is taken off. Taking the head off when you have low liners heastens failure.
