I would want to angle the throttles up some like the jenvey manifold since we don’t need to keep them level like carbs. It also gets them up away from the exhaust and looks better in my opinion to have the trumpets pointed up a bit. I realize it would counteract the goal of your up swept runner a bit by pointing the injector a littler steeper down but the amount of wall wetting with that short runner and the angles will be minimal. You could also just put the injector at the port like oem’s do and spray the back of the valve directly since you are making your own intake. Though I guess if you are using a e88-e31 etc head the center intake bolt hole will not be there and thus you will have a hard time getting the injector right at the port.
