im pretty sure they might fall for it, buttttt if they know there ford engines they'll notice that a 94-95 engine has a black intake, and has distributor, and that the 96-97 engines have a silver intake and has DIS. But its a good idea to swap that 94 engine with a 96 and newer one, since the headgaskets werent a problem. I think that when my cougie blows another h/g im going with a 96-97 engine, im not really fond of that 4.2 since its going to be a mission and cost more to be installed. Dude why this question are you worried about your h/g's??????? what im doing is flushing my coolant system every time i do an oil change, so my coolant is new. I read in that 3.8 headgasket thread that for longer durability of h/g's, your coolant should be flushed when you do an oil change.
