Cam change

I was wondering how hard it is to change the cam. I was reading some manuals and it doesn't sound too hard but just wanted some pointers. I already have the intake off and about to take the heads off to replace. The only thing I can see that would scare me is getting the timing right.
 
it's easy man. when you have the heads off, turn the motor over by hand until the #1 piston is at TDC. right before you start putting it all back together, stab the distributor so that the rotor is pointing to the #1 post on the dist cap.
 
Thanks for the info first time taking an engine apart. It doesn't seem as hard as I thought. Is there something I should check on the cylinder walls and pistons since I have the heads off? Also wondering if anything needs to be done to the lower half since the upper half is being replaced. Engine has 60K on it. Thanks for the help
