Doing some reading and it seems that not installing the head gaskets are the thing to do when rebuilding a TypeIV.
That being said, could the damage below be one of the reasons for a poor running motor? I was told that after the motor was rebuilt the PO had nothing but running issues and kept replacing fuel injection components on the Djet trying to hunt down the problem. Finally got fed up and threw a 2.0 from a wrecked car.    |

1 - Is everyone sure those are head gaskets? They dont look quite right
2 - Those sharp edges in the comb chambers could easily cause detonation. Detonation for no apparent reason might cause one to retard the timing trying to get it to stop. Retarded timing results in poor performance. 3 - I dont use head gaskets |
