Help installing camshafts.....
 

I have a 2.2L 4 cyl 5fse engine. I was paying someone to replace the headgasket, but apparently they did not know what they were doing and now I have to finish the job. He removed both camshaft from the head without setting the knockpin or the service bolt. I've got the bolt in the exhaust cam now, I think I understand that. I have installed now the intake camshaft, but how do I know if it is in the right position? An I know that there are timing marks on the rear of the gears that must line up, however the intake camshaft has now been rotated to about 10 degrees before vertical.
Do I need to rotate the lifters somehow for the exhaust cam to line up? Please help. This is my first time going this far with any engine...

And also...
 

If I just line up the timing marks on the cam gears will that be correct because the intake cam was rotated by itself, so I was afraid the lifters would all be out of sequence...
