Anyone have flow numbers on the -13 385cc with a 4.5inch bore?

On my first post I attached a flow sheet from modern on a 4.5 bore. Only reason I say for him to port the heads he has is it would cost him the least amount of money. Now if he wanted a Cnc port job and wanted the most flow he would be better off getting new heads as indy makes casting dedicated just for cnc program for the bigger port volumes. I went with t&d rockers on my -13's they oil through the pushrods as I did not want spray bar oiling like you need with jessel rockers. I was pretty happy with the flow numbers from the heads.
