The blisters disappeared when I chopped the intake manifold's carb mount flanges down about 3/4" and welded aluminum bends directly to the heads. I'm not sure if I'd do it that way again though. What I'd do (and may still do eventually) is mill the manifold flat, weld on a new aluminum flange, flange the tube also, and bolt the two together again. I think I could do that and only gain about a quarter inch in height over what I have now, and the cowling would still fit fine. That story is at http://home.hiwaay.net/~langford/corvair/intake.html . And I'd also like to flange it so that I can try different manifold designs to see what's best, such as the type where the down tube is part of a tee, like GPASC sells for it's VW applications. I'm in the midst of ditching the Weber and replacing it with an Ellison, which I hope to get in the mail today, so I'll be welding up a new lower manifold this weekend. I'm making progress, and I'm starting to see the light at the end of the tunnel... Mark Langford, Huntsville, AL N56ML at hiwaay.net see KR2S project N56ML at http://home.hiwaay.net/~langford
