[Broken135i]

Hey there! Im actually a 135i owner but figure there's more 335's out there.... i have an N55 and was wondering if anyone can tell me if i need to remove the cams go access the head bolts... also, do i need to buy the cam alignment tool/holders to take the head off? Im already buying the fuel injector removal tool, just wondering how to get the head off once iv got the VC off... i know its a stupid question, but its not obvious to me

Im not looking for the people that will say "if you cant figure it out then let a professional do it" iv done many head gaskets and am aware of the oddities of doing it to an n55.. just need clarification before i take it apart.. thanks!
