Think about it. At the beginning of the compression stroke, both valves are closed. If they weren't, mixture would exit via a valve, rather than compressing. Same with the power stroke; if you open the valves too soon, you're not getting all the energy out of the combustion. So you have both valves closed for a substantial period of time before and after TDC.

Just turn the engine until TDC. mic/set both your valves. Don't be turning the crank while you're doing that. Once you're done setting them, it doesn't matter if you turn the crank, and you can button up the covers at your leisure.
Thanks sounds great, I dont know why I seem to overcomplicate things just afraid I'll hear the ol'e " well didnt you do this/that?" lol.
But that sounds simple enuf, my way.
