I'll show him this thread and see what he says, but I think I know what he'll say.
When the engine is finished I'll post the dyno information, then we'll see who's taking the piss 
Mate, in all honesty we are only trying to help- geez, we have been for months.
We only want a good outcome for you, honestly. But it has been a little difficult, as you seem to have a fair gap in your knowledge (not being a smart-arse, we all have to start somewhere). the difficulty though, is that when you have asked for advice, over many threads, you often seem to ignore or discount the advice.
I get it, its the internet, and you do not know us from a bar of salt (we could be talking complete sheep shyte). But nonetheless, keep an open mind, and try to learn as much as you can about engines, as so you can hold a serious, informed conversation with the engine builder.
The single most best piece of information you have received was from OldJohnno, who advised you in one of your threads that you could copy a known combination. This is still the best advice for you IMO. Otherwise you are just entrusting someone with your hard earned cash who may be experimenting on the job. A known combo will get you the best results, for the cheapest money and the less stress.
