OK........thought about it more. Come at it from the other end.........from the valve train side. Make the area where the valve seats are as a removable plate so you can get into the backside of the combustion chambers and intake/exhaust runners to machine the water jackets. It then becomes much easier to seal off the water jackets into the valve train area without having to worry about combustion gas pressures.
