Can a Mazda B5 dohc cylinder head be swapped to a B3 sohc engine?

Swapping a Mazda B5 DOHC cylinder head onto a B3 SOHC engine is generally not feasible due to differences in design, mounting points, and compatibility of components. The B5 and B3 engines have distinct architectures, and the DOHC head requires a compatible block and timing setup that the B3 lacks. For successful engine modifications, it’s crucial to ensure compatibility of all components, which in this case, does not exist.
