416stroker said he contacted Edelbrock when he figured out the issue, they said they'd pass it on to their engineers and mold makers but who's to say they actually did it. If they did I don't know if my manifold was made before or after the fix as I bought it used off schmeeBay, likely before since I'm having the issue...
I'm about 95% certain. I've looked up at it from underneath with a good flashlight and the oil is coming from that corner interface between head, intake and block. The intake faces were also milled and the edges were all left sharp so they "dig" nicely into the intake gaskets when the bolts are torqued down. Last time I resealed it that corner stayed dry for a few drives then came back; if it was the head gasket the leak would still have been there. Not to mention I'm running custom-thickness Cometics with head studs, damn things better not leak! lol
