Lifter chipped on 8BA

[Fordestes]

I too have a pristine block except for a crack at the top of one lifter bore , it is about 3/8"X 1/4 chunk broken out at top, I am seriously thinking about sleeving the bore and stop drill the crack as to avoid the crack from migrating on down into the valley of the block, I have never sleeved a cracked lifter bore, I am thinking mabe a bronze sleeve, Opinions wanted.
