When you change nitro percentages, you will need to adjust your needle settings and also start your break in process all over from the start.

You do not need to break your engine in all over again.
Adjust your needles and go from there.

Generally engines don't mind going up percentage, but i think going down is not good.

Just readjust the needles. you are just resetting the needles to adjust for the different ignition timing of the different %'s.

It is just a matter of personal preference but I always found with big blocks that going to a higher % needed a colder plug. 20% I liked a medium plug.
I have had 4 of these engines with the lst2/8ight/muggy.
