How to set timing on a 1996 mitsubishi eclipse 2.0 DOHC

I changed the water pump. And as you probly know this involves alot of removing things. What my question is. I was taking the timing belt off and the cams spun a few teeth on me. I see the cam gears marks but can only see the block mark on the crankshaft. So where should the cam marks be and were should the crankshaft mark be? There is a white mark on each of the cam gears and i see the arrow on the block for the harmonic balancer
