From my looking at the EPC, it seems that the petrol engines don't have EGR nor IACV. EGR is only to be found in the diesel, the throttle body does not have a separate IACV.
I THINK with a damaged head gasket, there is little chance to achieve smooth idle. Pressure loss on the cylinders should be measured to ensure they are still good.
