Flows 300 intake, 215 exhaust
Been here before, I am a huge fan of buying a bare head and having someone that ports for a living do the assembly & finish work. Spare no expense on a good port job, they usually cost @ $500 for a nice street/performance setup. Darts are known entity in terms of porting results, as is Brodix , Edelbrock Tricks etc.
I personally don't trust the "out of the box or as advertised" statements,,, if a head is that good, the mfgr should flow the heads and send you a flow sheet.
I am having the factory clean up the chambers and port the exhaust and intake slightly to get me to the numbers listed, that's what I need for this motor. I don't want to over port them and have too much head.
