Aussies (Rapter) have heads and a low boost super charger for the 3.0R. Link is for one with an IC; there is another one without the IC.
If you search for Raptor threads, there is more info.
There is a thread for 3.6R headers. I think the OP is contacting Raptor to see about an ECU tune. The headers differ between the 3.0R and 3.6R.
On a good note, the 3.6R intake/exhaust valves are bigger; the heads flow coolant to the cylinder block/head independently vice the from one end to the other on the 3.0R; bigger injectors and bigger alternator.
