Will a 4d56 non-turbo engine cylinder head fit on turbo block?

No, a 4D56 non-turbo engine cylinder head will not fit on a turbo block. The cylinder heads for turbo and non-turbo 4D56 engines are different, as the turbo engine requires a different combustion chamber design and other modifications to accommodate the turbocharger. Using a non-turbo cylinder head on a turbo block can lead to engine damage or poor performance.
