Sleeves?

Wet sleeves have o-rings to seal the coolant. Farmall A, B, and C have wet sleeves.

A sleeved farm engine is designed to allow on the farm full overhaul. All wear parts are replaced with no need for a machine shop.

IH put a non sleeved C-153 in the 504 in 1963. That was the beginning of the end of sleeves in gas engines for them. It was also the beginning of the end of gas engines in IH tractors. Europe went diesel in the 50s. By the mid 60s Canada and Austrailia were 90% diesel. Since coming to YT, one of the things I find hard to believe, is the numbers of 60s, 70s and 80s gas tractors in the USA, particularly larger 6 cylinder tractors. I've only ever seen one 6 cylinder gas Farmall in my entire life, and IH started using those in 1958. I've seen thousands of 6 cylinder IH diesels, bought my first one in 1962.

I had "heard of" the gassers, but had never owned one.

Bought one of the silly things. Nice, fun little tractor, but having a hard time trying to get it weined from the fuel barrel.

Never again. Farm tractors and gas just don't mix in my humble opinion. :>)

The venerable 5.9 Cummins used in the Dodge pickups is a "parent bore" (no sleeves) engine.

It's block has a high nickle content, and apparently they often rack up 300,000 miles without major wear, because the nickle makes the block very tough and wear resistant.
