Frank, that would be helpful. I can handle trimming the hood inside frame if necessary.
I wonder if there is any relatively fixed point on a manifold that the height up to the front carb pad could be measured - and then compared to another manifold. Like to a valve cover bolt or something. My engine builder is trying to help but he's primarily into engines and not ERA street cobras and he doesn't have a good yardstick to compare to.
I finally figured out these 390 HP heads are pretty much the same basic casting as the 427 LR head, except for smaller valves. Port dimension appears to be same as for both MR and LR 427 heads. But, from the posts by Anthony and Barry above and from what I can find - It sounds like the MR port is physically raised a little higher up in the head. I guess I really need a LR 2x4 intake if I can find one. It doesn't sound like a MR intake should even match up with these heads (?)
Thanks - my FE education continues.
