Last night a friend of mine came round I'd not seen for about ten years, I speak to him regularly but he lives down south and was working up here for a few days so he popped in, he told me he was bringing a present (a little â€Ëachill-cig') lol. 
After a take-away, a few brews and the present he brought we chilled for a couple of weeks (might have been two hours —a not sure) before he said he'd have to get back to the hotel as he was up early, I was still chilling so I went on the PC and couldn't believe what I was reading!
What an angry little man I must come across as!!
I read over and over without realising I'd been spelling someone's name wrong totally unintentionally (seriously it was a red mist oversight) REGGID please take my apology seriously!! I'd not seen the woods for trees and should have taken a step backwards before engaging in conversation on the forum, everything I'd written could be taken in more ways than the one I intended —a so I'm sorry for that too.
The GRAPH that started all this misunderstanding still hadn't been answered really as I read it from a different (very different) angle, please allow me to correct some wrongs.
When a graph is presented to a customer I then spend the next halve an hour explaining exactly what it all means and how it relates to the head, the rest of the engine and put it all into context with the rest of the bits they have, I came in half way through this thread and just saw red from some of the comments I read and the way it was all panning out.
The flow graph was never meant to replace a Dyno graph but show ONE SPECIFIC PART UNDER TEST/IMPROVEMENT and the values those improvements have brought to that part, CFM directly relates to power but as REGGID pointed out so rightly it's not a Dyno which I never said it was, the Dyno was the next port of call.
As soon as it's been on the Dyno that graph will be posted as â€Ëaa Dyno graph' let the discussion start again once that value is known.
Right I'm off to do a 100 lines “ I must cut down on my coffee intake & learn to read “

Apologies all round & REGGID for what it's worth you can have two valves flowed for free, 50 quid a valve normally!!
