If you were topping a 460 with an Edelbrock Torker II I could help: the manifold was made incorrectly in the area around the distributor at the front.

Incorrectly means that the manifold did not overlap the china wall, so a bead of sealant had nothing to adhere to. The manifold was cast with its flange about 1/8" to the rear of where it should have been. Leak, leak, leak...

The fix was to form a 1/8" wide piece of aluminum and adhere it to the front of the manifold with some diesel sealant. After that cured, installation was successful and no more leaks.

Takeaway: dry check the manifold's fore-aft position and assure the ledge on the manifold actually sits directly above the china wall, and not behind it, so as to contain the sealant bead effectively.

Oh, and Edelbrock says "their manifold is not at fault," of course.
