Thanks Max, I saw that on Youtube actually. I've pulled the head off and it was warped slightly, it was higher at the corners where the bolt holes are and dipped in the centres. I put the edge of a steel ruler along the head and it sits flush at the bolt holes but you could see daylight easily under the rest of it, The valves are seating fine and the head and inside motor are really clean, no carbon build up at all, so i've cleaned all that up and have since machined the head so there is no daylight showing and just waiting on a new head gasket and i'll reassemble it and try again.
