When I replaced my water pump back in July, I ordered the new bolt kit. The new bolts in the kit are not blue-headed. I don't think they need to be replaced (BMW must have changed the specs). The old bolts and new bolts were exactly the same except for the blue paint. The bolts hold the aluminum water pump to the the magniesum block through rubber bushings. There is not much torque required to hold the pump in place. The old bolts are not torqued to the point where they stretch and break if you reuse them.
