If I do replace it, what brand should I replace it with?

I believe as the chain stretches, the intake and exhaust valves open later and later in relation to the crankshaft. I believe that is called 'retarding' the camshaft, not 'advancing' the camshaft. I think retarding the camshaft will cause the engine to lose bottom-end power; correct?
