    Default Not sure

    Not sure what the 120 refers to, but normally you can get away with (1) a plastic mallet, (2) a "dead blow" soft faced mallet, (3) soak the existing gasket with either diesel fuel, or Marvel Mystery oil..... Usually a good smack with a plastic and/or dead blow will jar it loose......AGAIN, I'm not sure what 120 means, so don't go beating on a fragile, thin walled, tube header on some exotic engine.......Ray
