That's why it is MANDATORY to degree the cam, any cam. That cam has a 113 LSA, so you would need to degree the intake lobe to 109*. That will make it 4* advanced. If you want to put it in straight up, degree the intake lobe to 113* There is no way to know which key way will work for you, hence the degreeing process.
