OEM Rocker arm help!

[sil80]

I am doing a rebuild on my sr20det and need a quick and easy question anwserd. I tore the engine down around 2 years ago, and I have built it back up good so far. I did not lable the rocker arms and now I am trying to find out if there is a order to installing them. Out of the 8 - four of them say M8 on the bottem and the other 4 say M7,M5,M5,M6. I have mic'ed them out and belive there are all with in .002"-.004" of each other. Any one ran into this problem?
