That chart is ok, A simpler more accurate way is to do each cylinder separatly, and you don't need to follow any sequence. I always start with #1:
Bump the motor until the exh. rocker starts down, adj. intake on that cyl., bump the motor over again and watch the intake open fully and just as it starts to close then adjust the exhaust on that same cyl.
Doing it this way assures you are always on the base circle of the camshaft.
As far as getting the motor hot, I never do, that stuff is to hot in there and you get oil all over everything. And there is no real way to keep the temps the same through out the sequence esp. with alum heads.
