the ps are off later 302 explorers and the manifolds bolt up the same but the postion of the spark plugs can cause spark plug wireproblems with normal headers, the x's are an aftermarket aluminum head by ford racing

thereis no comparison

the x are like a nfl team playing a middle school football team

p's are explorer heads, like stated x are aftermarket aimed for performance.

p's are iron, x are aluminum

i won't even go anymore....just take it for what it is

If you're trying to decide which one to buy go with the X heads.
