[5.0LiterBird]

If you look in the back of 5.0 mustangs and superfords or muscle mustangs and fast fords i believe there is a company that takes stock heads and does alot of nasty porting and polishing as well as adding oversized valves i think 1.94/1.60 . dont quote me on this but i believe they are 400 bucks. But working at autozone i tend to browse through the computer alot and i believe i have found gt 40p heads in the computer for 170 bucks a head. I dont have the casting numbers off of those heads but its worth checking into. I would appreciate anyone who knows the casting numbers because i would liek to buy a set of these heads. Just have someone look up heads for a 5.0 liter explorer from 1998.
