Busted Fazer - what are my options?

leave the exhaust on so you done break any more,if you can wire brush or similar areound the nuts and spray wd40 or something that will help but il bring blow torch etc to hopefully remove the others without snapping,each one i did took nearly a hour but the engine was in bike so pain to get to!
you of course need new studs and maybe gaskets ? while bike is in bits do you want do owt else like plugs,filters,etc you will need new coolant 
even if you remove tank,chain and  maybe some bolts etc it all makes it but easyer for me but if you havnt tools dont botch it or mess it up as will take longer to do then!
