AU V8 models: Basic questions answered!

That's just where the power peaks at. And yes on these it's cam and exhaust related, although the 220 also had a light bit of head porting and a bigger throttle body, although the cam was slightly smaller than the 200.

Noob question I have a Auii Xr8 complete drivetrain kept everything subframe diff aswell I have a series3 xr6 but has solid rear axle and diff would the engine trans and driveshaft off xr8 Au2 sedan all fit in the series3 Au? ...

No. You will run into problems with trying to match up the solid diff to the driveshaft without modification.

Wouldnt call it head porting by a long stretch, the intake manifold was very crudely/partly matched from upper to lower,very dodgy factory work.
When i ported my 220 manifold i was shocked at how little was actually done as opposed to what tickford said was done,less than 2 mins work there.
I had no port work on my factory heads from memory.

Port clean up is probably a better description. Some heads obviously needed more work to the casting than others.

If only they had fitted some proper heads to them, rather than fitting higher flowing stuff on intake and exhaust, only for it to breathe through a straw using tiny factory ports.

They should have used the bigger alloy heads Ford Racing had at the time. GT40X heads I think they were? Or was it GT40Y?

Maybe not so much on the 220, but at least on the 250kw engines.

The T1 and T2 TS50 with the 220 kW version actually had those alloy heads. When the AU II XR8 went to 220 kW, they switched back to iron heads, T-Series followed suit.

Late model T2 TSs had the iron heads as well. I think it was around April 2001 they went to the larger valve GT40Ps

They were just alloy versions of the gt40. Same tiny port size. If anything the gt40p’s were probably better due to the chamber upgrades over the old gt40’s. Looking back at my Ford Motorsport catalogue from 98 they were the only heads they offered back then. The better, bigger port X heads must not have come along till later. I can find reference to them as far back as 2004 but i don’t know what year they were introduced. So they might not have even been available to tickford at the time of production.
