You SHOULD be able to re use vc gasket, but I would replace all others gor gp. You do need new oil, the oil in there is trash if a guide is broke. If you got a lil extra cash, and wanna do a real nice job, get 4 piece front end kit, and a steel timing kit from engnbldr, that way whole front of your engine is new, and dont have to wrry about if for a LONG time.
