I bought a set of Police Intercetor heads from an 86 diplomat 318.Cheap. I'm not much of a mechanic.I was wondering if anyone here could tell me if they would work on my 99 5.9.If so how would they benefit my motor. The casting number is 4027596Thanks.

 

Nope, won't work. Too much changed from the old LA engines, to the new style Magnum engines.

 

I kinda figured.Oh well thatey were cheap.I will give then to my son he has an old 318.thanks HeyYou.
