Good to know, I see the term thrown around quite a bit while searching for engine building knowledge and I am a noob when it comes to this stuff. :)

I'm not familiar with using a torque plate for the actual boring, just the honing, because that prepares the surface for a good ring seal. I'd have to check with Gosh again, but I don't think he uses the torque plate for boring.

If you're just slapping a motor together and it doesn't need to be bored out, using a bottle hone is fine. They are hard to find, I couldn't find one locally, and there are two or three different "grits". I've used the bottle hone for a simple re-ring and came back with 180 psi +-2 psi in all cylinders, so it can work well for a budget build.

And to Brownman on the .040" over Wisecos. I'd take them at that price, 2.0 blocks are cheap, so if you had to go bigger, you just get a new block. Are these "stroker" pistons? Because you need the pins raised 6mm to do a 2.3 liter with a 2.4 crank with stock length rods.

Yea, mine is just a re-ring job basically. Stock 6 block that I was told had low compression because of rings.

They are stroker pistons. I'm waiting for some other prices to be available to make a choice.

Bottle hone, new rings, gap 'em to spec, done.

Bringing this back. What type of hone should be used for a DIY'er?

If you are just trying to break the glaze then a dingleball hone works well if you keep it moving smoothly and steadily.

Yep, those regular 3-stone honers from Pep Boys are tough to get a good finish with, bottle (dingleball) is the best.
