Message: [QUOTE="smokinstroker92, post: 1077801, member: 3595"] Yes the 7.3 heads can actually be made flow very well. Over 200cfms at 0.500 valve lift very close to the flow of 12v heads. If I where building a 2.6 truck I would machine the plenum runners from the head and fabricate runner intakes that direct straight to the ports this would help the flow a great deal more. The main restriction on the intake ports is the #2&7 I believe where the casting makes the port very long and narrow the other ports could be ported more but it is best to be flow matched. [/QUOTE]
