i will have stiffer valves springs and retainers to go along with the port and ppolish and 3 angle valve job. the combustion chambers are being honed and darton sleeved. would this work out with the stock cams to raise the redline safely or do they need to be modded to the 272's? where could i get 272's and are they usually really expensive thanks.
