Spark Plug Indexing

Spark Plug Indexing
Has anyone experimented with the spark plug orientation in our engines? Generally speaking, spark plugs should be pointed at the intake valves for max benefit, but engines are different.
Should I bother indexing them, or just leave it as random? I'm thinking it won't make too much of a difference as I don't have headers yet.

if you plan to race the car and are very detail oriented
it wont hurt anything to do that...assuming valves are adjusted spot on
but for your average street user with partially clogged injectors and carbon buildup on the pistons and intake valve backs....not going to do any measurable gains for you
*exception to the seafoam faithful who keep those parts clean and working 100%!
lets all align our spark plugs to True North and see if mpg goes up!
