On the lead bank (passenger side) the ports are intake in front, exhaust in back - look at your intake manifold runner compared to your exhaust manifold/header port location and it is obvious how they are oriented. Your intake & exhaust have some amount of overlap - you can see how much on your cam card - when the exhaust is closing as the intake is opening.
