Replacing chains & guides will take you some deeper into the engine. Front cover & oil pump has to come off. Locating new chains & guides could be an issue you would need to resolve before getting involved in the head gasket replacement. Would be a good time to replace the front seal & even the oil pump seal.

How many miles on your engine?
