Does this mean my 5th/6th ports work?
on my 86 gxl with 104000 miles i think the 5th and 6th ports still open up.. When i rev it slowly moving up until 3800 my exhaust sounds pretty much the same, and then it sounds like the rpms jump... this is in neutral. Does this mean my 5th/6th ports are still functioning?

On my rx-7 with stock exhaust and with aftermarket I needed load. Tried revving under the hood in neutral and they never moved. Did the grease test and the seemed to be working fine.
