headgasket will be fine mate, my pal changed into second instead of 4th at santa pod in his fiesta turbo instantly destroying most of his valves, he managed to find a head for sale at a trader stand so duly got the spanners out and swopped the head over using the 30,000 mile plus headgasket lol! it got him back home to preston
i asked him about 2 months later if he had swopped it for a new one and he still hadnt lol! i wouldnt reccomend reusing to this extreme tho haha
