as far the knocking goes you will either hear it, or the check engine light will come on.
for timing you i guess you need a adjustable timing gears, bnut i'm not sure. i think the stock gear can be modified but npot to that extent as the aftermarket ones.
and why the 87 is scheaper and better ? well 87 is made for most of the cars, and it does not require so much distilation (and purification) as the 89,91, 93 and 94, so there the technological process is cheaper. Many of the higher price cars (like caddys) like to go only on premium and plus. If u will ever go into an older one with analog display it will say premium fuel only.
