Proper gap on tr6 plugs

After my cam swap I replaced the spark plugs but have recently discovered a high speed glazing on them. So I Am switching to tr6's my question is what gap should I run on a stock compression cammed ls1 at 414rwhp

Have you ever seen a yellow spark plug like that? Figured tr55's were good as long as no spray was involved

I've seen that when the gap is too big. If you were running tr55s, your gap was too large IMO, I'd run a tr5. A tr6 may be too cold in your app.
