Not in any appreciable way it won't. It might limit cap walk, but that's not the problem. It might limit cap flex and distortion. But again, that's nott he problem. The problem is the main webbing, and the stiffer and more rigid you make the caps/pan rail, the more stress goes directly to the webbing. The best answer, if a stock block HAD to be used, would be 2-bolt aluminum caps. These will flex a little, but save the block for a long time.
