Default Help with misfire

Can anyone familiar with one of the scan software packages (I have the Ease package) tell me how to interpret the Misfire results? I traced MisfireHistory for each cylinder plus Total Misfire. Is there an acceptable limit on the count? My damn engine light is blinking under WOT!! #2 and #7 seem to be particularly bad. I checked the wires which seemed to be ok. I guess I'll pull the plugs in a couple of hours unless I need to scan for something else. I do have H/C, headers, etc. I seem to have misfire at idle and at WOT really bad, but under normal driving it is pretty much zeros.

I did recently purchase LS1 Edit. The only things I have changed are fan settings, idle rpm, and torque management.

Does it sound like a bad plug(s)? Should I just reload my stock ls1 file to see if that cures it?

Thanks.
