What to clean cylinders with before bolting heads down?

I want to be sure all of the debis and other crap is out of my cylinders before I bolt the heads down. I already used the shop-vac to get out the loose stuff, but I'd like to use some sort of cleaner and a rag to get the harder to get stuff. Would something like carb cleaner work? Or maybe WD-40 or Triflow?

if you are talking about the carbon deposits on the pistons, seafoam and wd40 do a good job loosing it up, but it still take quite a bit of elbow grease to get it all off.
I wouldn't use strong solvents.

I just hit the cylinder walls with a generous shot of WD 40 and wiped them clean. Can you post a pic of what you're talking about?
Edit: Pulled the excess out with a shop vac before wiping.

Why is there debris there anyway? When I did my HC swap the bores did not get anything in there. If there is debris in there the easiest way is to coat the bores that are at BTDC with regular motor oil and turn the engine over with a ratchet on the pulley. Once all 8 bores are done you will see that the oil on the cylinder wall will attract the dirt and it can be wiped out. Have a helper slowly turn the motor over by hand with you wiping the debris off the walls when the piston is on the downstroke. HTH
Why the ATF? I don't see the purpose. It's thinner in viscosity than engine oil and has less additives.

I was always under the impression that it was higher detergent than motor oil. Also, I would think it would burn off quicker than motor oil because it wouldn't leave as much of an oily film in the cylinders or on the rings. Motor oil would work just as good.

I agree, people have been putting ATF in the crankcase to clean the inside of an engine for decades.
