Is that the front of the cylinder ? if so that could be an extra boss for an accessory of some type to bolt to or maybe a spot to tap an oil galley running up to the top of the motor to oil the valves ? either way the metal separating the two has gotten a small hole in it and it would be smart to fix it if you can b4 the hole gets bigger.
