damaged cams

[cbutler]

So I am in the process of installing my BC 264s and when I go to take them out of the box and put them in for the first time I noticed the one tab is broke off on the intake cam. After searching in the box I found the broke off piece. I'm guessing this must have happened during shipping but definitely shitty!
So my questions are...
1. What is the purpose of this tab?? It's between cylinders 4 and 5 (1 being front most) on the intake side. I was thinking to pick up cam position sensor or something but couldn't see anything.
2. Can it be repaired by welding or can I run without it?
Damn, I was hoping to get this finished up tonight! Anyways any help as always is appreciated.
Thanks,

If there is another one just like it by no3 cylinder then ya its for the cam sensor. I would just send it back and get another. Who knows if it was shipping and having a bent cam or if it was a shitty casting or some thing.
