The valves are numbered from the front, 1-12 or 1-8.
Is the Haynes method the Rule of Thirteen (or Rule of Nine)? Subtract from 13 (or 9) the number of the valve that is down, and adjust the valve whose number is the result. This ensures that the adjusted valve is on the back of the cam.
Numbers are not the thing for some people. You can also imagine a mirror across the middle of the engine, between cylinders three and four for a six cylinder, or two and three for a four cylinder. See which vales are down (two at a time) and adjust the valves that are in the mirrored position. I won't try and demonstrate this by quoting numbers as the method is intended to avoid numbers - go and look at your engine!
Good luck,
John
