How much of a difference would it make if my spark was higher in the combustion chamber then lower? If any at all.
One side of me is saying that the higher it is, the less pressure from the explosion there is from the spark point to the barrel. Then the other half of me is saying regardless of where the spark is, it will set of the gas all at once creating equal pressure. I don't know which side to believe lol. Help?
Ignition height
Well... id keep it in the middle of the chamber and in the middle of the diameter of your pipe... You should try to get as close to the radius as possible.. Im thinking that by doing this the "Explosion" can expand up and your chamber and across this way it would create 2 explosiones ... 1 going back and 1 going forth .... if your using a spark strip for ignition I would recommend you putting it in the middle :]

I highly doubt you'll be able to tell any difference unless you're shooting uniform projectiles over a chrony.
Higher....lower??? What do you mean by that? Ideally keep them in the center of the chamber and equidistantly placed along its length. If you have 1 gap, place it in the center...2 gaps place them at the 1/4 mark and the 3/4 mark....3 gaps at the 1/6, center and 5/6 mark. These will allow the most efficient (fastest) simultaneous burning of the chamber with the spark sources available.
What I mean is, basically imagine a 2 foot long ABS pipe. Now I have two screws drilled into the pipe at an angle so that they come in to just barely meet, I don't know the gap distance but I do get a decent spark. Now just imagine where it is I have these screws screwed in on the pipe. Rather than it being more to the back of the chamber, say at the 1/4th mark, or even in the middle, it's a bit up someways. On a 2' pipe, we could assume the middle is at 1'. So my screws are drilled in approximately at the 1 1/2 mark or so.
