FWIW, I've used Bianchi's method on several heads and had no trouble With damage to the head. Visually the bores look fine and there is no evidence of damage on the OD of the guide.
I must admit, I did not measure the bore diameter but the new guides only go in after heating the head, freezing the guides and a bit of persuasion (using the Jim K. tool).
