Ok, we are on the same page. What I’m telling you is a sleeved block (done correctly) will be BETTER a than a block that isn’t sleeved. Simple as that.
It may be counterintuitive, but it’s a fact. That’s why I said sleeve it and move on.
BTW, there isn’t an aluminum block out there that doesn’t have sleeves in it. All of them. The sleeve materiel is better than the original block is.
