Has anyone done any experimentation with head gaskets by creating extra coolant transfer ports in the head gaskets? Many of the coolant transfer ports between block and head are blanked off by the head gasket.
I don’t profess to be an engine builder but I have torn down and rebuilt about 4 or 5 of these engines. Some engines appear to show obvious signs of the heads running too hot because of the visible oil stain coating the inside the head and yet others are quite clean. Yea it could be the quality of the oil used but I have noticed a small difference in the head gaskets, those that seem to be cleaner usually have an extra small coolant transfer port in the rear of the head gasket. I’d like to know whether there is anything to be gained by creating (drilling) some extra coolant holes in the head gaskets. Especially towards the back of the engine. Feedback would be appreciated.
