Do i need the dowel pin in my CAM? im re setuping up my motor. and the dowel pin had previously fallen out and i found the dowel pin just wondering if i need to try and re install it or just use the 3 bolts to old it in.

You'll want to re-install it. It's added insurance against bolt slippage, plus it does a good job of locating the cam sprocket onto the cam snout.

Why are you tearing down the motor? Didn't you just put that Trex in there? Hard to say if it is damaged or not. If the pin was in when you installed it and just fell out when you set the cam sprocket aside I would wonder if a vibration from a bad spot in the cam made it pop out. I have pulled them out of stock cams before and it is a PITA with a pair of vice grips even.

I would have the cam checked out. You don't know if it got nicked or warped. Something might have happened to it. I wouldn't want some little part to ruin my brand new motor. You'd feel really dumb if you made two huge mistakes in a row that both cost you a motor.
