Quad 4 timing marks

I see this question a lot with no answers dont know why. Well anyways on the crank line up the pulley key with the dot on the block.on the cams (DOHC) theres a little hole about a quarter inch on both cam sprockets those two hole should point straight down, there is a guide hole behind the cam sprockets were you insert a 8mm bolt through the sprocket and into those guide holes. now you have the cams set; the bolt also keeps the cams from moving on you, wow isnt that easy. Now if the car doesnt start just rotate the crank 180 degress and wala there you have it. I went to farm&fleet and peeked in a haynes manual.
