no mate, its only the inlet ports that are different to accomodate the injectors

ive actually ran an efi xr3i on a 1.4 manifold because before i sold the car i swapped exhausts with my mate so they are definetly interchangable

No.

Any performance exhaust for a 1.4/1.6 CVH (i.e XR2i) will be more than ample for free flowing gases.

you might make it breath a bit better higher up, but it may be a bit gutless lower down.

you don't want to be overfueling it to much with a larger carb, it could wash out the cylinder when you put your foot to the floor, before it starts sucking in the correct air to match the fuel.

Do You Mean with the cam, or the ported head?

Last thing I want to do is creat problems for me self, I just want a good, 0 to 60 sprint car, And If this cam only caters for top end, I wont bother with It

with a 0-60 sprint the revs are going to be at least 3000+ all the time, this will cause no problems as the engine is already working hard. It would only affect the car from low in the rev range say 1200 in 3rd.(when you put your foot to the floor. the affect would only last for a second or 2)
you want a quick car so everything will help. you may have adjust your driving a little, the power band may move up the rev range.

my original quote is really based on town driving.

He means the power will probably be moved higher up a little, so you might have to rev a little higher in gears around town etc. Shouldn't be too bad though, if you do all this other stuff it might be at least the same at the bottom anyway.
