Someone on here said they did that so they could swap heads without having each one o-ringed.

The iron OEM sleeve is not always centered in the casting. We have cut alot of o-ring grooves in LT 500 cylinders. Sometimes the groove is partially in the iron and partially in the aluminum. A small crecent of alumimum or iron will break out when machining making the groove too wide on these poorly centered castings. On the hard running 500s cutting the o-ring in the cylinder can cause some detonation issues.
