One of the holes you can drill straight down through to water no problem the other hole that is near the head bolt hole you have to angle a bit so that it goes to water too. I never thought about the angle but 45 degrees sounds like way too much.
If you try to drill the one thats near bolt hole straight it will either never hit water or will come out half way and very likely grab and break the drill bit. Might want to practice on a scrap casting first.
The holes dont have to be very big.
