More Gen 3 questions

I'm after some info on the Gen 3 Hemi crate motors .

I have a line on a full plug and play 6.1 - but ts the EFI version and I want to go with carb induction.

As we don't have MP dealers down under - the questions relate more to the product than the actual conversion -

1 - The crate 6.1 seems to not include the power steering pump, alternator and air con compressor - Is this correct?

2 - I don't want to run air con or power steering - so how is the serpentine belt set up without these components?

3 - The conversion I'm planning on will be using a carb fed Gen 3 using the Carb change over kit from Plum Floored creations

- Can I use the ECM that comes with the EFI crate motor, or do i have to swap it out for a custom one?

4 - Are there block hugger headers available for the Gen 3?

Hope some guys can help me out with answers on these questions - there may be more to follow but at this stage I need these answers.

Thx in advance.
