Question about marking timing components

[spyder97gs]

I've got to change out my camshaft, and i've never done timing before. Should I mark timing for the mechanic when I take it to him, or would it be better to just zip tie the timing belt to the camshaft sprocket and leave it tie'd on there until I take the engine in? I've got the engine out of the car. I've got a SOHC also. Thanks...

Look at the sprokets that the belts go around. Do you see little notches in them along the outer edge?

As long as you follow the proper way to put it back together, it should be no big deal to completely disassemble it.

Yep I see them. So nothing really needs marked if i'm gonna put another belt on, correct?

I went to rotate the engine, and it came to a stop, like it was hitting something. So i waited 10 minutes, and it rotated fine and continued to rotate fine. Surely that wasn't a valve hitting a piston. It couldn't have been could it? Timing is still intact and in time. I'm just curious what it could have been. I didn't try to force it, so I could have just needed more force.
