Damaged lifter bore - sleeve or hone...
The pic below shows about 1/3 inch off the bottom of the bore. I can bronze sleeve it for $275 at a machine shop which is not bad, but I am concerned if it will come loose? I slightly honed it and the lifter moves smoothly up and down, but I am running a .613 lift on btr dual valve springs and there is a lot of pressure holding that lifter down. Anybody ever run a damaged lifter bore this size or had any of them sleeved?

Been seeing this a lot lately and I've also experienced this myself although the damage was less severe than yours. Personally I would go bronze sleeve and save for a block after, just in case.

Yes, I am going to bronze sleeve it. I plan on taking it to a machine shop Monday. I need to take the rotating assembly out and it will be ready.
I think that the lifter roller/bearing wore down (80k miles), coupled with some possible cam wear and it slipped out of the lifter tray and turned and then the cam snapped it. I have 162K miles on the car. The first time I had lifter failure (https://www.camaro5.com/forums/showthread.php?t=396773) was around 82k miles, so this must be the max it can handle with my cam lift (.613) and dual valve springs lol! I keep going back and forth to put a forged stroker in it or not since I am in about as far as you can go.

Why not hone/bore to run a .903 lifter?
