175 Fast Strike block rebuild

[bass_guy67]

I have 1992 175 Fast Strike, model VJ175GLENC. It has a crack on the top of the head. So I'm planning on replacing the head with another.

I have available two 150 heads: The crank case on each are: 1: 0436719
2nd: 042999.

Does anyone knows if they would work on my motor.

Thanks
