If I understand henry's post correctly, one cylinder was sleeved and the remaining seven were bored. Anyone that has good experience building engines knows this is a big no-no.

Back in the 'day', I did some checking on at least two flatheads that I had. I used the 'thread' method to check 'big-ends', then 'total'. Pistons were matched to 'originals', as I have never found what stock was, for 46-48 59 engines. This seemed to work ok, for the street engines that they were. If there is a published number for 46-48 pistons, I'd like to know it.
Regarding sleeves... sometimes you just 'have to'. Seems to me, a properly installed sleeve works ok in a street engine. On the flip side of this comment, I've seen a few examples of sleeves not done correctly. Old posts on this board have explained properly installed sleeves. One example of 'bad' sleeves, I posted awhile back about an 8BA engine that appeared to have been assembled with a near-standard piston in what appeared to be a 3 3/8 bore. And, it came in as a running engine. It turned out, after disassembly, it was found that cylinder HAD a sleeve, and the remains of that sleeve were in pieces in the pan. Situations as this give a bad name to sleeves.
