Got some more done on the engine this weekend.
Although I don't have a stud extractor as of yet, I thought I would cheat and weld a nut on to each of the rounded bolts to allow me to get a socket on it.
Rounded bolt, moral of the story - don't trust a garage!
Nut welded on..
Success!! Bolt extracted..
Finally, cylinder head off to reveal a non OEM head gasket that by the looks of things was in the process of failing - again, don't trust a garage!
