PLENUM for 2.5L Build

So, one of the ideas i wanted to make sure i addressed was the ability to goto a Cosworth Style plenum vs. stock intake. So, i reached out to a manufacturer, and searched the web.

1. Here is a pic of the 2.3L Head inlets i found on another forum
2. here is a pic of the 2.5L Head inlets below it (credit goes to the other forum poster)

3. The manufacturer says the bolts will line up, however, to get full advantage of the airflow capabilities of the plenum - a bit of machining can be used to open up the inlets on the plenum side

Here is a pic of the inlet side of the plenum style i will go with - my thought is to machine out some of that metal to insure it is matching the head side inlets in diameter.This way my TUNER has more air to work with.

Engine is supposed to be delivered friday !!!
