good numbers for the leak down experienced.
The most flow I have got out of a 906 head using the stock replace 2.08 valves and with no valve job 'just a used lapped in stock seat' so far is 278 cfm.
I have only done one port, no.3 I think it was.
My suspicion ....was that my calibration was off, and it was....hence the re test and finding of 278 cfm.
It seemed a lil too good to be true so I had to ask others ;)
