Set the piston at TDC, then put on the sprocket for the cam with 2 notches parallel to the top of the head and have the other notch up. Now just attach the cam with the lobes facing down. And it should be timed. Unless you are looking to degree the cam, for precise timing, which isn't required with the mods you have listed.
