cyclinder head help

[snowbrew]

Two years ago I bought a cam and cyclinder head kit from clifford preformance. Yesterday I pulled the valve cover off the head and found that the bridge between the rocker arms was bent. Each of the bridges was bent to some degree, some worse then others. This has lead to the rocker not centering on the valve. The springs that came in the kit are a lot stiffer then the origional springs.
I have tried to call Clifford, but the phone is no longer avavilable and their web site is no longer available. Called aftermarket companies such as comp cams, and jegs, but they did not help.
Anyone have this kinda trouble? Or heard of such a thing.?

Thanks
