WOW! yeah you most likely are blowing some spark out!
A good rule of thumb for ignition would be that the smaller the gap (with stock ignition of course), the higher boost. I would try maybe a .024. Also, the copper plugs work extremely well, nothing too crazy. You'll have to change them each time your change your oil, but they seem to do the trick based on my experience with FI.
Secondly, what temp plugs are you running? If you're running stock heat cycle plugs, you may want to go about 2 to 3 steps lower for that much boost.
Reason being that with a stock type ignition and distributor you can only allow a certain dwell time and spark for each plug, so the wider the gap, the less precise the dwell time and spark, you might not be blowing the spark out persay, but you could certainly be knocking or sparking at the wrong times.

After some thought I slapped myself for not including the analogy:
Try getting a lighter to work when its REALLY windy out with the flame all the way up, then try lighting it with a smaller flame, same principle. Harder to blow out.
