Default Input on plugs/wires for larger displacement engines

Just trying to get some input on what larger than stock displacement engines or even aggressive H/C setups that will be running NA are using? I am running about 10.8:1 CR and using stock wires and NGK TR-55s now.

TR6's with Moroso Ultra 40 race wires. All bore 382 solid roller. The wires almost make dynoing impossible as the pickup unit can barely read the spark!!

I ran TR6's gapped at .048 with MSD wires with my 11.75:1 iron block 422ci.

Isnt a TR6 better suited for nitrous or forced induction because they run colder? I didnt know people were running those plugs NA, but I guess both of those setups are more radical than mine...

I ran my 9.82 with stock wires. Worked fine for me.

Accel 9000 wires here with NGK-55's.

The wires are real good for headers; I lost 2 stock ones in a month due to header heat.
