I dont know about the autolite, but i use the NGK's in my T/A.
Whatever you do, DO NOT use the stock GM plugs if you are going to use nitrous.

I've seen the 103's used at 200+ jetting and they always looked great. goodluck

do you have an O'Reillys auto parts store close to you? if you do then go there and get the NGK plugs for 1.99 a piece and they come with a one year warranty and just take the old ones back and get the new ones when needed.

Autolites are a nice plug. Nothing wrong with them at all.

if the tr6 plug is comparable to the auto lite 103 then if your using a tr7 plug what auto lite number would be comparable?????

They really don't have much in that heat range. The next step up would be a AR474.

Will the TR6's be ok for a 150 Wet Plate kit?

Yep, the TR6`s will work great N/A and with the 150 shot.
