camshaft break-in

We put a new comp cams 268h cam lifters and springs in dads 273, we THOUGHT it had dbl springs, but it turns out that it was just dampers on the inside of the springs. We were kinda lost with it...we called Compcams and told us they were not dbl springed, just dampers. I have heard/read that with dbl springs, the inners have to come out....
