ERA Chas: Thanks for the gouge. I checked the website. Nice stuff, and the price definitely reflects it!
Olddog: Thanks for the observations. The tunnel wedge intake is an air-gap design with a removable bottom plate to close up the lifter valley when the intake is installed. I envision the injectors external to the intake, just mounted on the underside of the runners, still pointed at the intake valve.
Here's a linky to a picture of the intake manifold:

I may have to settle and have the injectors on the top of the runners. Hiding them in the middle may be beyond the point of diminishing returns....
