From a few different machinist that if you hone your cylinders instead of using the actual boring cutters, will actually strengten the cylinders. Example: my 4 bolt block is .032 already and my used trw flats wont work. He ordered .040 SRP flats for me. He sent my block to his buddys machine shop to be put on his boring machine but hes gonna hone 9 thousandths instead of using the boring cutters. Then he will fit hone the cylinders himself. He does this to every engine he builds. Hes owned and been building race engines for over 30 years and has never had one returned due to piston/ring problems or cracking cylinders.
Maybe something to look into. Maybe there's less vibration with using the honing technique or maybe because it takes longer on each hole,the honing tool heats up the cylinder more thus making it harder???
