So I'll be putting my top end back together soon, and was wondering what your preferred method is. The top end has 18k miles on it, with still visible cross hatches and I'll be installing new rings. I'd rather just deglaze with a scotchbrite pad and not take off more material then needed, or should I buy/rent a ball hone. What do you think?

Deglazing won't do it if you want the rings to seal. Even though you can see the cross hatch pattern the surface is smooth and will not seat the rings properly. Ball hone as per the maintenance manual would be my suggestion.Comment

I got mine from enginehones.com. They are relatively cheap to buy.Comment

Ball hone the cylinders if you want it to run better. A TRUE honing, taking out MINIMAL material would be best. Ray.Comment

Got my dingo-ball hone from enginehones.com. They have a page to help select what grit to use. I bought 240 grit, which is a little coarse for chrome rings (stock Suzuki), but my rings sealed well regardless.Ed

Well I don't want to do this again unless I have to... I bought OEM rings so a 320 grit ball hone would do the trick?Comment

Didn't see you had bought new rings for it...Comment

So it looks like I'll be getting a hone, but the thread on resurfacing has me questioning if I need to get my heads done. I don't mind doing it but if I can save the money ($75 from the local guy) I will.
I had a brain fart and slid the head on some cardboard, which gave it those scratches... The worst one is in the last pic, you can feel it with a fingernail but it doesn't catch it. Should I resurface?Comment

Around the cam chain tunnel, you could polish a small scratch out and be OK. For low pressures like inside the crankcase, an o-ring will easily take up ~.05-.08 out-of-flatness and still seal, as long as it's smooth.
I'd be more worried about the pitting around the chamber in the first pic. The out-of-focus area in the foreground looks pretty bad.Dogma

I took a look at it again with the old head gasket, and it looks like the pitting is inside the fire ring so it shouldn't affect the seal.
The rest of the sealing surface looks good actually, there aren't any defects that will cause issues except for one. There is kind of a bothersome scratch on the head, it looks like it has been there for a while. Maybe a manufacturing defect?
