I found them to be rather hard to find, but supposedly the block is safe to bore to 3.905, and 3.898.. I thought it was a bit too much boring(stock size being 3.78 on a 5.3/4.8 block).

You are going to have to bore it to stock LS1 3.89 or go the overbore 3.905, there are alot of pistons for that app.
