carb off, rocker cover off, exhaust manifold unbolted, mark up cam belt with tippex on all pullys, remove spleen bolts on head from the middle out and in diagonal opposites (these will need replacing) and then lift head (after unbolting whatever waterpipes and sensors are attached) make sure block and head is VERY clean, new gasket on and then drop the head on and replace everything in reverse order. Whilst at it do your cam belt and cam tensioner, also worth thinking about your waterpump too. Not even close to a comprehensive guide, just an idea to keep thinking through in your head. Makes alot more sense if you open your bonnet and read through.
