i'd just install my Type C TODA camshafts into my B16A engine head. According to diagrams inside Cam box from TODA, it shows that when i advanced my intake cam to 109degree, the diagrams showed that i should retards my exhausts cam to 111degree. As i know, if we degreeing our cams to advanced, we should advanced both of it. How come this diagrams showed that intake in advanced and exhausts in retards?
Anybody here can help me to solve my problem.

At the moment i don't dare to do any adjustment on my cam yet.
