You are in control of your destiny. You can make it whatever angle you would like. Generally, you are looking at 45 degrees. If you do a lot of work in wood with difficult grain, go up to 50ish. You can also make a scraper plane up in the 85-90 deg range. I don’t suggest going to the low angle in wood. It just gets too thin to support the iron well.

The throat is also up to you. You want to get it to the point where it won’t hold too many shavings so they flow out well. You want it big enough to get your fingers in to clear it when needed. You want the mouth well supported so it doesn’t start chipping out.

What I have done on mine:

I went ahead and made the the front angle about 50 degrees. I then glued in the front block closer to make the mouth too narrow for the iron to come out. When the glue was dry, I opened the mouth with a file which left a blunt edge on the back of the front block instead of a thin knife edge. Several planes later, no problems with any of them and they all work just fine.
