Peter - Thanks for sharing your experiences.

Two vac ports are in the manifold valley at the rear. You can see them in a couple of the photos. I don't know if I'll use either of them as I don't have power brakes and I may not be using MAP sensing for the ecu due to the large cam I've got.

I did note there are no rear water bleed ports, so I may follow your lead and add them in similar to standard ford efi manifold I'm using presently.

I agree regarding re-positioning the injectors, but don't think I'll do that as it will be a race only motor, hence light load/low speed driveability, emissions and economy don't rate for my purposes!
