It seems hard to get responses about 6.0 builds around here. I am doing one now too. Anyway, I dont know why you would have to replace the crank. You may want to replace the pistons to up the compression.

Most likely the pistons and crank are OK, but have them checked. It would be a good idea to place the rings and have the block honed to clean up the cylinder walls. If you decide to replace the pistons to increase the compression level, I would overbore the block 0.030". Also do new cam, rod, main bearings.
