The engine has two times it is at top centre indicated at the crank in the otto cycle. On the power stroke initiation both valves are closed and the injector has just finished squirting. The lobes are pointing upward. The next time it approaches top centre it is just finishing its exhaust extraction from the power stroke and the inlet valve is starting to open to admit fresh air for the forthcoming power stroke. So the lobes are generally pointing downward to activate the valves.
So if you where to rotate your crank one more turn the lobes will be upward. Your real problem is to find out if the number one injector is spraying on the right stroke.

So far you have just got the engine up on its exhaust and intake stroke. You do not yet know if the injector is spraying at that point or where it should be really activating at the initiation of the power stroke. You have a little more work to do. If you find this confusing another way to express it is one rotation of the crank will place the cam timing mark 180 degrees from the next turn of the crank. The injection pump turns at half the crankshaft speed as well. The relationship between the cam and injection pump can be easily disturbed when removing and installing a head.

Thats why you should make sure the cam mark is on before removing the head just before you removed it. Then after the valve job install the head again in a fashion that duplicates what you had. Paint marks on the cam sprocket and chain are also a good refference to use by the way. Otherwise you run a fifty/fifty chance of getting the cam relationship to the injection pump wrong.

You still have to verify what stroke the injection of fuel on number one cylinder is occuring. You can use the line with the injector in the open air or the welling up method in the number one injection pump element. The welling up method you can read about in the archives should be good enough for your purposes. Easier to manage as well in my opinion.

I may have misunderstood your post but think not. If you want to see your cam lobes pointing generally upward just rotate the crankshaft one more turn to top dead centre indicated. Also ask any questions that occur to you so members on site can attempt to clarify anything. There is yet no proof that you are out of sequence just because you see the cam lobes pointing down.
