The muriatic acid cleaning is an excellent idea. I don't use anything after that except a flood of good clean water.

I bolt a head to the opposite side of the block, and torque the main caps. Then I pour the first side, and immediately install a cylinder head and torque it. I let it set one week. Then remove the head on the other side, pour that side, reinstall the head, and let it set another week.
