Helo my name is joe live in jax Fl. I have a 97 sentra that blew out a spark plug so i removed the head and had it re worked. now when I went to install the head, the head gasket on 3 of the cylinders does not match the water jacket holes. so I went to get another one and it is the same. Do you need to cut out the water jacket holes, or is the gasket correct and some of the holes get covered?
