Ok, so I mounted the intake on the installed engine, no gaskets, and from the top of the crown of the valve cover to the top or highest point of the intake, was 5 3/4”. I suspect that is less than a stock carb and air cleaner. For fun, I took a photo using a level, since it is straight, from the top of the cowl, not on top of the cowl seal, to the top of the front hood closing stops just to see if over that run, the intake was above that plane, and if wasn’t. Had small clearance below it, but still, I’m sure the hood is still higher than that.

Again, not intended to show clearance, but as a relation to a plane. I suspect if someone did this next photo with a tradition manifold, carb and air cleaner, it would give a good idea if there would be an interference (The level is sitting on the inside step of the apron, not on top of the fender, if that isn’t clear).
