Ford Repair: Cam setup 4.6L Romeo, crank shaft, cam gears

Question
The books (Clinton and Haynes) say to set the cam keyways "perpendicular" (at a 90 degree angle) to the head surface and the #1 piston at TDC (135 degrees), but when I set the cams and lock them down the dots on the gears are 180 degrees off. I can't seem to match the dots on the gears to the black links on the chains, so I'm afraid to put it all together, for fear of being 180 degrees off. This is a Cloyes chain and gear set p/n 9-0387sj. Is this the right chain set for a Romeo engine, and what is the RIGHT way to set the cams up???
Thanks ahead of time...

Answer
the cranks shaft gear should have a dot on it. set that straight down. the two cam gears should also have a mark. lay the two chains on a flat surface. the black marks on the chains should be opposite each other. when you align one black mark from the chain to the crank shaft. it should line up with the cam gears. also, go to you tube. type  " how to set the timing chains on my ???? " you will be able to find a video on how to do this.
