Head gaskets and engine flushing...
Looking at the crap that has built up around the water holes and the size of em on the old head gasket I have to wonder that these small holes covering large ports would be a real restriction to any activity that tried to flush the engine.
Dirt, rust would just build up behind these holes. Wouldn't it be better to just allow the full water flow through which would allow for better cleaning, etc..
And I know the holes are smaller to suit revised cooling plans and increase coolant flow around the engine where it is needed more...
