PI head swap ?s
 

I am doing a pi head swap for the first time on a 98 GT. The heads are off a 99 s281 and the intake is off of a 2000 Grand Marquis. What are all the little bits and pieces I may need to make the conversion? i.e. gaskets, brackets, adapters, anything else you can think of. What plugs should I use with these heads, I will want to stick with platinums for longevity reasons. The car is all stock besides Flowmasters, CAI, and Accufab TB-plenum. What about the cam gears on the PI cams, are there any criticle things that I may be ignorant about. Thanks for the help.
