We removed the sleeves from your block, re-machined the receiver notch just below the deck and installed new sleeves. After a week of "stress", we can not make the sleeves settle any more.



So it looks like they have it sorted now, but if any of you guys go dart, be careful! Might be more trouble then it's worth if your engine builder isn't really on the ball.
