Just tackled the big rebuild, backyard style. How does the initial timing setting (i.e., cam sprocket alignment, tdc, etc) look? I can't find an accurate description in my poorly translated manual. Do the marks where the woodruff key go straight up or 90 degrees from the head surfaces?

------------------

Forgot some minor details, there. It's an '83, with the double row chain. I've replaced all timing components, so everything is factory specs. (Big job, don't want to bend any valves on startup!!!)
