Ok the head is off, real pain in ass but its off.
BUT, There seems to be a few things that are not quite right.
On top of the pistons there is loads of debris looks like charcoal and on the top part piston shafts about 10mm down there is rust forming.
On the head it self it looks like its coked up ect I would just likw some advice is this normal>?
cheers

Dan,
Quite normal for there to be carbon deposits on the piston crowns, and for the exhust valves/ ports to have a layer of carbon over them. scrape it out of the head, but dont touch the valve seats when scraping. these will need to be ground in. wipe grease between the piston and bores when they at the top of their stroke- this stops carbon deposits getting into the gap when scrapping thr crud off the pistons. as for the bore rusting, use a peice of 240 grit wet and dry and lubricate with oil, the polish the rust out using side to side rubs.dont go up and down the bore.
