This has been answered many times over.

I head can be used. But you'll lower the compression. Good for boost bad for NA.

It's alot of work man... to set up properly.

You could just pull the rockers and shafts from the I they are identical.

Read some threads in here, some cover this topic extensively,

The I cam is different. If you swap the I cam in you need to swap the I ecu.

swap the whole i engine over to your eta or as suggested just pull the rockers.
