I have put two sets of head gaskets on my 1993 ford ranger both to no avail!!!!!! Felpro gaskets. Both leaked right off. When I looked at them they didn't have ports for the front they did for the back ports. All other holes were small holes. Why would this be? These are brand new heads wouldn't this build up pressure where there isn't access to coolant? It is a 1993 ranger 4x4 xlt. I thought it was a 4.0 but I'm starting to wonder. It has a sticker on front about spark plugs and it has 4.0 on it. I don't get why the access areas wouldn't be the size of the ports! I'm trying not to punch something right now I have spent hours on this thing and spent more money than I should. hope somebody can help me out.
