I've discussed it on other boards. There are a few options out there, even getting someone to notch one to clear probably wouldn't be that hard.

I'm contemplating a few things. With the turbo and exhaust locations it is more difficult to access the frost plug locations I've plumbed into, so may go back to the thermostat housing (by notching or fabricating one) and run the cold water into it and then still have water come out the block in the front.

The bigger reason I'm considering it is I'm thinking I may have to mount the water pump on the left side of the engine and it would be even worse plumbing getting to the frost plug ports on the right side. But I did buy the two port water pump so I could run to the frost plugs... decisions decisions.
