fly-cutting pistons

I have been soliciting advice from the good folks here about what to do to increase the performance on my car. I have a new 351W build with new forged flat top pistons and new forged rods. I am getting 450hp but I want more. I am running too high a compression (11:1) to bolt on a hair dryer. I would like to swap out the crank and increase the stroke but don't want to toss brand new pistons for which I just paid $600 bones. I heard about flycutting and want to know what exactly this will allow me to achive. I know it will bring my CR down. Can the pistons be worked to allow me to install a bigger crankshaft while keeping the CR to 11:1 or lower? Is this something fly-cutting is used for?
