haha im doing exactly the same job today. im going to paint mine
i have taken the head off as i managed to get crap down one of the exhaust ports. i have also managed to get a head and bottom end gasket set for mine with all new oil seals for the crank etc etc.
notice that we have both got exactly the same engine stand too. £40 from machine mart bargain
