Got a 383, need advice from my FABO brothers

Here is the block. I opted to not get the heads he had, so at this point I am not sure what heads to use- any ideas?

So, is the crank forged or cast?

I do not think the crank will accept the input shaft of the 4 speed, it doesn't seem deep enough. I have not taken my engine out, and this is the first 383 I've dealt with. Some say to cut the shaft, but I don't like that idea, so what is the correct way to solve this? Good or bad, I need to know.
