One tip for make sleeve installation easier while improving heat transfer is to lightly hone the cylinder with #280 grit stones after it has been bored out to accept the sleeve. A smoother finish inside the bore will improve metal-to-metal contact between the sleeve and block when the sleeve is slid into place.
