I needed a quick answer,but since I didn't get it I went with the NGk tr6 gap at 38...hopefully I get replies as to this being a good start to go with,thanks for any info

A TR6 is only one heat range colder than stock, use TR7's @ .045. I have a 11.5 cr 416 and run RS9YC Champions @ .045. And there not too cold.
