I will (hopefully) be swapping my heads and intake etc. onto a fresh 306 and adding my new (to me) P600B in a couple weeks. Should I have any work done to the heads while I have them off? They are Edel. 6032's and they have about 8k miles on them. They are box stock right now and I am not going to spend the $$ to have them ported or polished right now. I'm not sure if I should need a valve job or new springs or anything else fairly simple while I have them off the car. Any thoughts or suggestions? I'm running an RPM intake and will be adding an FTI cam that came with the blower (or maybe my TFS stage 1 cam???).
