I just changed the head gaskets on my 98 mark viii, when i started it up it smoked like hell , out the back and from undrr the hood, and its pulling air i think .and pressure built up in the coolant quickly, im pretty sure ive installed the exhaust manifold gaskets backward or upside damn down or something. Would that cause all tge pressure in the coolant thier is no thermosstat installed. Or have i put the damn head gaskets on wrong also?
