Why not just try and do it yourself there aint anything technical about changing your head gasket it will save you alot of money plus you will learn something new. It pretty hard to mess it up. All you will be doing is unplugging everything taking the head off. Might want to have it pressure tested. Cleaning everything up. Putting the head back on and torquing it and pluggin everything back in.I say jump in there head first LOL. Im sure there are plenty guys on the forum that will be able to help you out if you have a problem.
