What are the best brands and type for GN if improving top end speed is the goal? Appreciate the help.

Do a search on "valvesprings." There are a lot of different opinions out there but it depends on your setup, so research here first, then post info about your specific combo if you want more help.

Comp 980's are a common choice for a flat tappet cam.

Dennis Kirban has a set and sells a tool to do the job

I prefer 979's on stock cams.

Comp 979's with the stock cup or Comp 980's without the cup for a stock cam.
