For this reason all machining on sleeved blocks is proprietary so that we can eliminate any failures associated caused by 3rd party actions. Also since the sleeves are permanent for SR's we often recommend going with a smaller bore size such as 86mm or 87mm simply so you have room to mess up because you can go up all the way to 92mm, however; that requires custom pistons. By leaving yourself several bore sizes available your block lives much longer.

Thanks for clearing that up. I was reading up on Darton and found that, yep, their sleeves are not accepted by our AL blocks if wet sleeving, and that also may have been a failure mode (as compared to wet vs dry sleeving). From what I understand, the FWD guys were not using your process at the time
