I am not saying you can't get away with a port and valve job with new springs and hardware. Going that route is probably ok on something mild staying under 7k rpm. But if you are considering a more aggressive H/C setup with Nitrous on top it might be something to consider. Contact GPI or Pray and tell them what you are looking to do.

Sorry my notifications are turned off. $4,500 for reworked heads to work as good or better than aftermarket? Why not just spend less and get aftermarket that work just as good as aftermarket? Lol
