why are the water passages [shown a couple of replies ago] in the head gasket [cometic] so much larger than the block holes ? is that the shape of the coolant passage of "most" heads commonly used with this block ? if the head holes are close to the size of the block holes, would/could this shape in the gasket have the potential to cause cavitation or steam pockets ? or am i WAY overthinking stuff here ? TIA for setting me straight on this.
