Welcome to the wonder of interference engines. You are correct that the drawings are not very good.
1. The two camshaft sprocket marks (mine are blue) point straight up to the two 'arrow' marks on the valve cover.
2. The crankshaft 'V' slot on the inner plate points to the tip (at about 10 o'clock position) of the mount for the tensioner pulley. I know it does not really look like the hma drawing. I had to buy the Haynes manual to be sure myself.
3. The rear balance shaft sprocket (mine had a white paint dimple) matches the arrow (mine was painted white) on the engine block on the left at the 9 o'clock position.
4. The front balance shaft has a good drawing so use that one.
I did like you and gambled that I had not bent any valves. Do install your balance shaft belt, and timing belt. To get all the timing marks aligned, you likely will have to move the crankshaft. If you need to move the crankshaft more than 5 degree left or right ( no more than 5/16"), you can do this without harm. BUT that is highly unlikely. So make sure you remove all of the camshaft journals off of the two camshafts before you rotate the crankshaft more than 5/16". This will prevent the camshafts from opening the valves, so you can 'freewheel' the engine. Once you have the timing marks lined up, you can reinstall the camshaft journals and torque to spec.
After you get your inner balance shaft belt and timing belt installed, do not install the outer covers and belts yet. Static time the engine by turning clockwise 3 times with a 22mm wrench on the crankshaft. Use a helper friend up top to listen and observe the movement of the valve train for any sticking or binding noises. If your engine was like mine, you will hear 'plink' and the two bent valves will break at the bend line and drop into the cylinder. You will definitely feel if the valves are bent, as they will bind during the revolution of the engine. If the two valve heads break off, they will literally not let you turn the engine over so don't force it.
Since I had the head off, I could tell from the clearances that it is almost impossible not to have bent valves if you broke a timing belt. Sorry. I can give you a source for a cheap, fast, professional cylinder head if needed.
Where's my bailout?
