 Jim- I gave up on the stock clamps once I got up to around 12psi boost- It seemed like that's about all they would take before leaking, and as you found, trying to tighten them further merely bends the bolt flanges- I found a nice clamp from a Marine 
Hardware store locally- they are like a standard hose clamp except there's no slots cut into the band- they are formed indentations in the band and are much stouter and better looking than regular SS radiator hose clamps- here's a picture of
the style I'm using that I found online: http://www.hardin-marine.com/popup.aspx?src=/images/Product/large/100-720-6306.jpg
I've taken them up to over 18psi boost with no problems. The site that the picture came from also has the T-bolt style, probably close to the ultimate in band type clamps!
