h22 timing marks

[foumer]

whats up? My friends h22a recently had a water pump leak, so we decided to change it. I had to take the timing belt off. The problem is that I dont see any timing marks to go by on the cam gears. The cam gears have an arrow but the block doesnt, so I dont know where to line them up with. The crank pulley does have an arrow and another on the block. Any help will be greatly appreciated
thanks

the cam gears should have arrows
u line the arrows facing up lining with the middle of the camshaft rails (if thats what u call it)
but the cam gears should also have a horizontal straight line marking on the side closest to the engine. so you align the lines with the block.
