R45TS is what I like on N/A L69's and 350's. NOS, I don't use, but colder for sure...

Definitely go colder for NOS, but check them out after you've hit the juice & see how they look. It's going to be a better driver w/ hotter plugs; change for colder before going to the track. Tune from there!

 

For a colder plug you could go with R43TS and use the R45TS when you're driving around town.
