Flathead Ford when I was in college. There was a ridge at the tops of the cylinders. When I started it up it broke the top rings.

To bore and hone cylinders is usually only 20 to 25 dollars per bore.
Then how ever much pistons are.
When I get an engine I just assume it's going to get bored and have over sized pistons.
Hello oil_pan_4,

Huh. That's not a lot of money, about $150 for my V6. Does that include cleaning? What level of quality does that buy, from your experience, and from about what timeframe (was this the 80's/90's or more recently)? Do you get a "plateau" hone, for example, with the slightly rough (for break-in) but flat (to limit wear depth) tops with the ~45 degree crosshatch going deeper beneath it for oil-holding? A few of the links in my first post went into detail about the process.

Even if it is that inexpensive, adding all the new parts I'd want to "because I'm already in it this far and getting burned by a bad XYZ would suck" and new heads gets really close to just shelling out for a long block. If this was a truck I definitely wanted to drive for 5-10 years, it might be worth it. As it is, this is my "get back into it and learn" truck, essentially considered to be somewhat disposable. So I need to figure out if this is an engine I want to take apart and re-assemble more thoroughly or not.

I need to call around and find out how much it costs to clean and leak-check cylinder heads. If I'm just slapping it back together with new gaskets, no sense in spending $500 on new heads. I just have to not overheat it...

Anyways, anyone else have any luck in tracking down those SAE papers mentioned in the original article I linked? Hmm. I need to see if the library has them on their online service, which means I have to figure out what my library log-in number is, since IIRC it's different from my library card number.
