Now, when they did the rebuild, were the cylinders bored out to the next oversize or did they just re-ring it? What kind of head work was done? Were the valve guides in spec? I had shop put the wrong valve stem seals on a Honda engine before since they ha

I’d also like to point out that in order to properly measure cylinder wear you would normally do it at 3 points within the bore as most of the wear occurs in the upper third of the bore, they might not have measured in the right place but that’s just a th
