Weber intake manifold to fit 1.5 JB head?

Hi

I've got i 1.5 JB. And I want to run a weber carb on it.
- Is the intakes in my head the same size and shape as the more commonly tuned 1.8 counterflow heads?
- So a Intake manifold for webers will fitt straight on my head, plug'n'play?
- I've been looking atthe single DCOE manifold BFI sells, to be sure. You guys think this will fit?
Link to BFI single DCOE manifold.

Thanks.

They are the same as 1.6 & 1.8.
Only difference on later mk1 i.e. cabby, citigolf & mk2 big blocks they have a water channel in the inlet manifold to the block, this is located between 3 & 4 cylinders.
1.5 and 1.6 jb blocks do not have this i.e yours, but the inlet holes all match
