bolt placement for timing cover/water pump

ok, when I took apart this 318 a few months ago I actually took a piece of paper and mimicked the front of the timing cover to get the right length bolt back into its proper hole. Well, lo and behold, I've seemed to have lost/misplaced the paper (go figure!). Is it really that big of a deal or is it much to do about nothing. Don't some of these bolts go into the water jackets? I know to put RTV on those threads. I'm not as SB savvy as I am BB.
