Here is another tip.
The cam sprocket also has a dot in addition to the "L" and "R" markings on the camshaft sprocket. You can see this dot at the 11 o'clock position in the photograph below.
When you install the timing chain on the cam shaft, try to place this dot even with the top of the cylinder head on the right/intake side of the cylinder head. When placed in this manner, the "L" and "R" markings will be placed in the correct vertical locations. If you are satisfied with this alignment, you can apply some black RTV silicon to the cylinder head, and begin the final installation of the rocker cover.
