LS1 spark plugs?

[DoubleC]

Need suggestions for which brand/model spark plugs to install before I block access to them with fenders, hoses, and other BS. The 5.7L was donated by a 2001 TA w/ 52k miles. The only modifications are a set of mid-length headers. The only future mod will be a tune, if that. Fuel delivery is stock. Thanks in advance for the help.

I always ran the NGK Tr55's in my car back when it was still a car
