Intake Leak

I did open up the manifold bolt holes a little because they were rubbing a bit the first time I bolted the intake on. And I did check the shoulders on the bolts, all ok.
I can make any gasket thickness that I would need. The .030 lasted longer than the .060 gaskets. I don't think it's a thickness problem, more a angle problem. I just don't know how to start to get it corrected. Thanks guys.
