Will this work?

Rather than go down the extremely difficult route of modifying my existing manifold to take injectors I'm planning to manufacture two adaptors that sit between the cylinder head and the current manifold. Could the experts around here please take a look at the following links and comment on the suitability? :

I'm a newbie, haven't even installed my first MS yet. But, I do have some knowledge of cars, so here's my 2 cents:
I can't see why this wouldn't work, but I do have to question the angle you've got your injectors coming in at. The main idea is to have the injectors pointing at such an angle that the flow of atomized fuel is going into the cylinder while the valve is open, not spraying onto the valve itself. There's nothing overly wrong with spraying the valve, but you don't get as thorough burn of fuel because the fuel forms larger droplets when it is plrayed onto the valve surface. The numbers are minor, and more than likely it wouldn't even affect emissions testing of the vehicle enough to fail.
I say, if you've already got it spraying where you want, go for it and build it!

not necessarily.
spraying the back of the inlet valve is generally done for emissions reasons. from a power perspective, you would want fine atomisation of fuel, for better emissions, you want to vaporise it. that is exactly what happens when you spray fuel on to the back of a hot inlet valve.
there is nothing particularly wrong in doing this, many oem's have been doing so for years.
