My W30 intake seems to have very narrow lip thickness where it meets the heads. Could be the problem with it leaking all the time. Has anyone ever welded a sheet of aluminum to the runners and then cut the runners back out to make it thicker. I bought the thickest gaskets I could find but wondering if I could weld plates to that to add to the thickness. It is a 9/16/1969 manifold, it says OLDSMOBILE on it, don't know it those were thinner to begin with or if this has just been milled one or more times.

Any suggestions?

I have two 9-16-69 intakes,and I don't see any differences with the other dated intakes.Those flanges do appear to come to a point,almost as if they were milled-down,but I know these have not been.
Is you intake leaking around the water ports,or just everywhere?

uh not sure, I believe the drivers side back corner
