Default H22 exhaust port spacing

Does anybody know how far apart the ports are spaced? If anybody can take a mesurment like in this pic, and tell me what you get i would greatly apreciate it. I think this is a b series flange, but you get the idea

just pickup an exhaust manifold gasket.... cheaper, and u can transfer it directly to the metal, if you're CNCing, take measurements from it.....

Well this isn't for my car and im kinda broke so i would really rather not buy a gasket just for the spacing. Im ordering a pre cut flange from someone but i haven't been able to contact the person to ask him what it is.

Heck if i knew the cylinder wall spacing and piston diamiter that would help.

The bore pitch is 94mm and the stock bore is 87mm. You may find a helm's manual useful for whatever you are up to...
