If you're talking about iron barrels, the sleeves should be flush, just like the barrels were before sleeving. Unless you're thinking about early Atlas barrels with the raised spigot on the top. The spigot went away somewhere around 1966, so the Commando barrels were all flush.

If you have parallel liner fitted with no flange to locate it mechanically when pistons seize in the bore they can and do pull the sleeve down into the cases which is not what you want to occur as it ends up costing money!!.....
Wnen I bought a LARGE amount of weathered spun liner castings from Sheepbridge Eng in Sheffield decades ago (each casting made 2 liners) we always made Norton liners with a flange on the top end to stop the liner moving through the barrel. Somewhere I still have the machining drawings for them ..BSA Triumph and Norton and I know that in my loft there are still a few castings some for making 90mm bore liners
For parallel liners we (and a friend still does) always bought from The Los Angeles Sleeve Gear Co in the USA who did and I believe still do liners in 3 different thicknesses.
With a 99 tis no trouble to fit a flanged liner. Trouble is does anyone make such for Nortons. Bet an automobile liner book will list a few suitable but you will probably have to buy 4 .... assuming we in the UK still manufacture liners....Bet the old Sheepbridge works is a housing or shopping estate now!!

Dear DENNISGB.
If you had contacted me first before critisising I would happily of dug out the drawings and e mailed you a copy. AND IF you had arranged to visit I would of shoved you up into a loft to drag out a casting for yourself although where you would get it machined and ground as a one off I cannot imagine.
Manners cost nothing.

The answer to your question is simple, look at the underside of your cylinder head, if it is flush then you use a flush barrels. If there is an undercut around the bore diameter, then this head was designed to use a spigot barrels.
As a general rule, you really should not mix them up.
There are lots of stories out there about using spigotless cylinders with intented-for-a-spigot heads.
Just need to use the machined spigot rings - thats why they have appeared for sale.
I have an Atlas engine with non-spigot head and earlier spigotted cylinders.
Just need to have the spigot machined off, in a long list of things to do....

I tried to buy from LA Sleeve years ago to rebuild a non-Norton air cooled engine.
excuses and delays for over a year with instant money waiting .....no product ever confirmed or delivered even after MANY follow up calls and broken promises for a CATALOGED item.
I'd no longer WASTE my time with this company that only wants to deal with big corporations rather than local machine shops.
??? Do you hear the chinese companies sliding in and up your posterior ????

My point was you constantly talk about how "so and so" told you or you have documentation or drawings somewhere...or parts in your loft to substantiate your point...but most of what you say is your negative opinions and not helpful at all. I don't need you to dig anything out...but maybe you should find the documentation and actually post it with your babble...just once to show that there is something behind what you say.
