Jarrid,
Why bother to try to remember all that? The only possible advantage I
can see is being able to set the valves by rolling the engine over by 720
degrees (one full cycle), instead of twice. I still say it is simple to
renumber the valves 1 thru 8 from front to rear and use the "magic number 9".
Even a completely inexperienced person cannot make a mistake identifying
intake vs exhaust valves, as long as they can count to 9.
Below is what you wrote, (with my additions in parenthesis):

#1 intake is full open, adjust #4 intake (valve 2 + valve 7 = 9)
#2 intake is full open, adjust #3 intake (valve 4 + valve 5 = 9)
#3 intake is full open, adjust #2 intake (valve 5 + valve 4 = 9)
#4 intake is full open, adjust #1 intake (valve 7 + valve 2 = 9)
#1 exhaust is full open, adjust #4 exhaust (valve 1 + valve 8 = 9)
#2 exhaust is full open, adjust #3 exhaust (valve 3 + valve 6 = 9)
#3 exhaust is full open, adjust #2 exhaust (valve 6 + valve 2 = 9)
#4 exhaust is full open, adjust #1 exhaust (valve 7 + valve 1 = 9)
