Here is some info on upgrading the 200 I6.
..Swapping to a 170 I6 head will increase CR to approximately 9:1 and this head has bigger valves.
..A .030 mill on the head gasket surface with removal of sharp edges and some polishing in the chambers will raise even more for use with premuim fuel. Valve pocket clean up,port matching and clean up would be of help.
