okay so I replaced my HG and my did the timing belt on my ca18det, i go to crank it and she just cranks, I go to check the timing and the new belt is toast, the teeth are just destroyed for the most part, I have someone crank the car so i can look at the cams and they aren't moving but u can see the crank pulley, sprocket, w/e is spinning, anyone have a clue what I fucked up? btw the Timing was dead on and i torqued the camshafts down to spec

Dude, as a practice, you should always spin the rotating assembly manually, meaning with a wrench on the crank bolt, before you start the car the first time after a major repair/install. You've obviously bound something in the head, pull the valve cover and take a look.
