Use Felpro Intake gasket 1250. Its a fairly easy job to change the intake and roller rockers, should only take a day if you take your time.
Only problems you might face is if some of the sensors don't fit. I think you will find the AU manifolds don't have the ACT sensor in the 2nd intake runner of the lower manifold. You can easily relocate this sensor to anywhere in the intake piping, the rubber hose between the throttle body and MAF is the easiest.
You will also have to run your EGR spacer (the part between the intake and throttle body). Although the EGR system will no longer function, as long as you hook up all the connectors, the EEC will not throw any fault codes.
The TPS sensor on the AU throttle body will also have to be changed with your old one and modified slightly to fit, or modify the wiring loom to use the AU TPS.
