[QUOTE="Matt90GT, post: 1352302, member: 30871"] call your local dealer for the torque specs The cylinder head does not use a gasket. But 2 O rings. If the head is torque to spec properly, then you either have a warped head or cracked head and/or cylinder. it could also be installer error pinching the O rings To fix the head, have a machine shop mill it down .010". Give you a bit more compression also. But you may want to have someone magna flux the head and cylinder to see if there are cracks in it first. [/QUOTE]
