<p>when you are ready to install the cam, you want to check a couple things:</p><p>1:make sure the piston is at top dead center(the highest part of it's travel) you can be sure the piston is at top dead by removing the inspection plug on the alternater cover. when you remove it, when the engine is at top dead center, a small mark with the letter "T" will line up with the marks inside the plug hole.</p><p>2:install the cam with the lobes facing straight down. when you have the lobes pointing down, there will be a few marks on the cam sprocket. you will see small lines on it, and those lines need to line up with the cylinder head horzantlly. so when the cam is install lobes down, the marks on the sprocket will be side to side.</p><p>3: then you want to install the cam chain, then recheck the mark on the flywheel cover to double check the top dead center of the piston. </p><p>4:the install the cam tower/valve cover, and then the cam chain tensioner. make sure you turn the engine over slowly by hand beofe you use the starter. if you have timed it wrong for any reason, turning it by hand wont bend a valve because you will feel the piston hit it and avoid any damage.</p>

There isn,'t any lines on the cam shaft sprocket. All there is is just a littlle dimple on the sprocket and one on the cam shaft that lines up with the two bolts
