which b18c are you referring to? there's the itr b18c and gsr b18c. the itr b18c and b16 do share the same pr3 casting. the gsr b18c has a p72 casting.
differences include different bolt patterns on the intake side, pr3's have a bigger combustion chamber, different valve angles. they're both the same physical size.
they're stamped either pr3 or p72 right above the exhaust ports
