Hi Anna,

Its the early HEADS that get machined for sealing rings; the cylinders simply get a small cut to aid the process.

If your 100mm P/C's are in excellent condition well within spec, you can have them machined for sealing rings. If they are close to, or beyond spec, I would recommend the newer ones that use sealing rings.

Your heads do not need any specific work to accept the later cylinders.

Hope this helps,
