Hey folks, just doing a little work in the garage before the game starts. My question is: What do you folks use when cleaning up the top end of your cylinder walls? I am talking about the small carbon build up not a ridge. Just pulled the heads and have some carbon build up. Just wondering what you folks do? I have some ideas already but am open to new ones.
Thanks in advance for any input
Are you planning to pull out the pistons? If the shortblock is staying together, that carbon is taking up wasted airspace between the piston and cylinder at TDC and isn't hurting anything.

yep. I would not use a ball hone or a ridge reamer unless I was pulling the slugs outta the block.
I dont' care how meticulous and clean you are, you'll leave trash in the gap between the piston and cylinder wall. That'll scuff your cylinder walls and ruin your ring seals. I've seen it happen many times during head swaps. More power initially, but then it drops as the trash on that top ring land does it's damage. Leave it alone, it's not hurting anything.
