How are those TR6's burning? Most tend to find them pretty cold for a stock pulley and low compression.
You should also be able to run a gap upwards of .060
they burn pretty pretty good no left over fuel! lol, i gapped them that low due to a miss at high rpms, when gapped @ factory .55 pulled the plugs re gapped them no miss and made almost .75 aof a second faster at the track.
