Something is for sure up. My NGK 8 heat range plugs are gapped at .030 and had no issues with 24#'s of boost. I have a friend who is running 30#'s of boost on his plugs also gapped at .030 and no spark blow out there either.
I also had ran a set of side gapped Autolite plugs for a while. I changed to NGK just because my tuner didn't have a lot of experience with Autolite's but from what I researched the side gapped Autolite's are actually very good under boost. They never gave me any problems (neither have my NGK's either though). If you are at the point of throwing money at it, you may want to give a side gapped plug a try.
My point here is mostly that I don t think the gap is the reason for the blow out. There's something in the tune, the resistance or signal from the coil that's not right.
