All the sidedraft manifolds I've seen will fully cover the inlet ports on an injection head. Despite what is often said (including on here) so will
most Ford downdraft manifolds also.

Vulcan manifold
Aha, a can of worms question... 
The '205' only came as injection as far as I know.
I'm led to believe that the reason the engine has more bhp is because the gas flowing is better in the '205' cylinder head (as opposed to is being
because of the injection).
see:
http://www.pumaracing.co.uk/pinto.htm
Bear in mind the '205' has pear-shaped inlet ports as opposed to the circular 'carb' Pinto.
I wouldn't want to argue with anyone about being able to fit carbs directly to this (205) head I don't know enough to speak with authority. All I
wish to point out is that Vulcan Engineering sell a manifold to go from weber carbs to the '205'.
A picture of it is here:

It costs £87 +vat
If you choose to use this then with air filters you will need 9" between your head and the chassis rails to fit it in.
See, nothing but facts and no opinions!

We've run a fair few rally escorts with pintos before now, most with the 205 engine (thicker block, hence stronger, ish) Had single 45 webers on
these with no problems, so I cant see any problem with twins.

The 205 block was also fitted to the Transit (in factoriginally fitted to the Transit AFAIK). And they didnt run injection either. BUT most, if
not all, will have low compression pistons fitted, means that you can run on any cheap poo fuel you like, but not good for power.
Cheers, Stu.
Dont just build it.....make it!

The 205 engine in the sierra runs at 9.2:1, not exactly low compression, you can check it by looking at the chassis plate, it will say N4 or N4A in
the engine section.
You can run it on unleaded but you must turn the timing back 4 degrees to 8 BTDC

Pinto
Pinto injection heads have a slightly different port shape that flows better than a standard head, this head is commonly fitted by stock car racers
they are heavily restricted to what porting they can do. the main area that is workable (worth while working)is quater of an inch either side of the
valve seat, I would recommend balancing the bottom end of your engine, there is no point of buying or working a head when the other half is'nt in
"tune", also gives you a chance to make sure crank and conrods are not bent! . Also buy one of the many books available an easier read is How to
power tune Ford SOHC by Des Hammil. Without spending silly money you could get 140 bhp a slightly wild cam would be a good option, as no doubt the one
you got out your doner is sh****d and the spray bar will be full of crud! one last thing there i have heard there is a cut of point for which pair of
carbs to go for 40's 45's around the 140 150bhp mark. A coil pack with electronic ignition will help to keep things running smooth, look out for
Classic ford mags as there are plenty of articles on tuned pintos and spares for sale!! good luck with your build.
