Is there a manifold specific for the st170 head for dcoe style throttle bodies given the different port spacing?

So everyone running Jenveys on a st170 is using a manifold with ports that don't line up! Brilliant

I would guess anyone with half a clue would port match the manifold using a gasket as a template.

The ST170 and Zetec are exactly the same flange and port spacing

The only difference is the roof of the port on the ST170 is 1/3 bigger than the zetec so any aftermarket zetec inlet will need to be fettled to match the cylinder head

Agreed. It was/is an urban myth from, as far as I could trace it, the US Ford Racing manifold which in its original incarnation was not machined for the Zetec head, and the non symetrical port spacing at the plenum/manifold joints when used with bike TBs.
