Chad the Willpower doesn't stick down below the flange like the stock intake. It looks like the sealing flanges are about a 1/4" below the flange. Here is a pic of the Huffaker intake on a plate:

The plate should be no less than 1/8" thick and being cast probably at least 3/16" to avoid casting flaws and possible leakage. Thicker at the block flanges of course. I think it would be a pretty good idea to include a small flange that drops down inside the lifter valley along the front and back of the block but of course it would make production machining of those places a bit more work to set up. I expect as much as a 1/16" gap on each one would accommodate variations in the block casting. (allow shifting of the intake fore/aft by as much as 1/8") This flange or shoulder would help retain the OEM seal and make sure it didn't drop inside during assembly. It's true that the seal has lips on it for this purpose but it would just make for a nicer fit up and a more positive seal.

Does anyone still use a rubber seal in the front/rear?

Underside view of Wildcat intake which is made by Willpower. Looks like a 5/16" plate from flange to flange would be perfect.

Wanted to update and submit for future reference on how we got here. Without a block Anthony is guessing on the valley plate dimensions but we came up with some good measurement values and hopefully this will be enough to fabricate the valley plate. Some pics. This engine still used a valley seal though rtv will need to be used with new manifold. There is only about 1/8 gap between bottom of manifold and valley wall. Anthony wanted measurements from the intake edge to valley plate.
