Hi all,

Recently picked up an 03 Sebring LXI 12 valve 3.0 SOHC 6G72. My question is this; will the 3000gt base model 24 valve heads mount to this engine as they are both set up for SOHC timing chains? I know the engine is mounted in the opposite orientation (trans on driver side), but are the major differences in the head casting itself, since it's the same block architecture? Curious if since head gaskets are probably due, changing to 24 valve could net some relatively cheap gains. Further, would the ECU tune be different for airflow changes and would it be beneficial to get a 3S ECU with the heads? Had a couple 3Ses, but new to Sebring coupes and understand it's based on the 3rd gen Eclipse. 5 speed, which I understand makes the ECU a bit simpler since it doesn't have to manage a transmission as well. Would a repinned main harness allow brain surgery? PFA [leave the VR4 OUT of this. 😁]
