Myth made up buy people thinking it can be done. it can not. the best you can get is file to fit rings. these are a little long and need to be filed to correct clearnce. 4.030 rings will not fit inside the stock 4.00 inch bore correctly even without the piston. Just use the correct sized rings if the rings dont fit you need to bore the block or buy the right rings. best to have it measured up and see if its correct and what size parts you need to buy.
