Mine seem to be perfect.

I'll take a measurement sunday, I have to pull the engine out of the car, so I'll have the intake off.

My injectors might be the medium ones. I have had four different sets on this engine over the years and I alwasy have to change the fuel rail heigth. I forget which length they are.

I have a set of 220# injectors and one set of Mike Moran 500# injectors I would love to grow into some day. That would take nitro to get to I think. Might use one or two for meth injection in the charge piping.

This is how mine sit, the injectors are fully seated and my rails bolted on without any mods.

Something to keep in mind. With the increased heigth (angle) it looks like this is a deep as they can make it. I have had no issues with the fuel hitting the injector boars.

We will see on the dino next month. So far idle tuning has been a breaze with this manifold. The car is not far enough to do any other tunning. Idles great at 700 rpm and 14.5 afr. Plugs are clean. I would think if the fuel was running down the bores I would already have issues.

Your bungs look taller then mine to me. I think mine are closer to the lines on the outside of your last bung in that picture.

Looking at my pics maybe they are the same. Hard to tell from pics.
