I have a couple holes through my spars also, The one thing that I followed was the practice of structural steel beams of keeping the hole in the center of the height and there is also a formula of hole size to web height that tells you when you need to start to reinforce the web. But none of it may apply to a wood box spar. This is just what I did and your results will certainly vary.
