news to me: I have a sleeved block with an Apexi HG. I will have to ask my builder and ask Mazworx, who did my bottom end about this, but so far I have no evidence of an HG problem and my motor puts down some good power. Anyway, I can't think of why someone would ever want to sleeve a block for 350whp: it is completely unnecessary.
