well i had a guy tell me that i have PI heads on my 98 mustang GT can anyone tell me some easy way to identify if i really do have PI heads without having to rip it apart? i have been told that the oil fill cap will be on the left side of the engine if i do have pi heads but mine is on the right and then people have told me my valve cover bolt pattern will be different? but as far as i know it all looks stock?

to my knowledge the 98 did not come stock with pi heads.

No, you have NPI heads.

only way to tell is either a stamping # off the heads or pull the intake manifold and sea if the ports are square (pi) or tear-drop (non-pi) ...the oil fill location is not 100% correct....now Romeo PI and Non Pi heads will have 11 bolt cam cvr, so if by chance you count the cam cvr bolts and have 13/14 then thats a Windsor head and could quite possibly be PI heads.
