engine cooling question I'm not running a water pump, and there is the 4 holes on the front of the block, does it matter which ones are in and which ones are out? I'm assuming the top ones are in.

I am not certain on this but based upon "theory"...and we know how that goes...I would think the top ones would be going out of the block with the warmer coolant (heat rises). Strictly theory!!

its all -8 and yeah it will flow plenty. its fairly high pressure 75-85* fresh water. open cooling. run a single inlet and dual outlets as to prevent from pressurizing the block. as for the expense, I have a buddy hooking it up so all the hose and fittings were right around 170$

Awesome job or your boat BTW. I too, over the years, have made many parts with a jig saw, sawzall, drill press, and upright belt sander. You can do a lot with a little as long as you are willing to spend the time, and you take pride in your craftsmanship...and I can see you do. For the last 3 years, I have had CNC equipment available to me...cutting the piece out is quick but the CAD work takes some time. If you need more then one piece that is the same though, it is great.
Once again, great job, great craftsmanship

P.S. The top holes are out...they lead to the heads, the bottom holes are in.
