A rigid / precision hone should really be used with a tq plate on the block. If you're just deglazing a cylinder, use a flex / ball hone
Looking for recommendations on what to do with hurt cylinder

That's good, because I prolly got the shadiest of repair trees on this one.

First picture is cylinder 1, this cylinder had good compression and you can just BARELY catch a nail on the score. Second picture is cylinder 5 that was low on compression. You can just BARELY catch a nail on either score. The rest of the cylinders looked good to me. Picture number 3 there is a few high spots where rust has built up on the deck of the exhaust side. What's the best way to clean the deck? Didn't have a chance to pull the pan yet and wont for a couple days.

Thanks I actually have some of them already. Engine was on original headgasket, when I did head studs one for one 30k miles ago I was able to blow a lot of coolant out of 7 or 8 of the holes. When I pulled the studs this time there was no coolant. Assuming maybe the head gasket had a slow leak, and the studs sealed it up? What makes you ask?

I'm looking at pics on my phone, but to me looks like those cylinders are pitted

I would get you one of these hones, to be sure that your bores are not out of round when working on cleaning them up.

They make different grits of stones and different adapters for different cylinder sizes.
Those two scars don't look like you should be burning that much oil like previously stated your rings probably are wasted on #5.

I noticed the same thing, im going off of memory but it seemed like each cylinder wasnt pitted the same amount, and one cylinder had no pitting. I'll clean them up and get some more pictures tomorrow.

To the OP: Can we get more details on your failing cam shaft?
Engine oil brand?
Oil additives used?
Oil change interval?
Were the tappets new or used when mated to this cam?
Valve spring details?
And of course, cam mfg and approximate date purchased. I understand if you're not wanting to post the mfg name on a public forum...

1 bottle of Lucas zinc at every oil change
New tappets, same brand as cam
Factory valve springs
Cam was purchased 1/21
Id rather not post mfg name at this time.
Lash set at 010 and 020,checked 3x inbetween install and 17k because I was worried about this exact issue, assembled with moly lube. Broke in using mfg instructions to a tee. Here's a few pics, there's not one good lobe left tbh.
