Cylinder to Sleeve height

[littlebill31]

I painted my cylinder and baked it in the oven. Of course the cylinder dropped a tad so the sleeve was higher than the cylinder/head sealing surface.
I put it back in the oven and then used weight to get the sleeve flush again. Tapped a little to get it flush.

But this got me thinking. How much is too much or too little?

Right now my sleeve is a tad higher than the surface. Just enough to catch a fingernail. Using a razor blade as a straightedge, I can barely see light.
Is this a concern? Should I have it milled down?

I don't know how it was before this happened so I have no base.
I have another cylinder and it too just catches a nail, but not as much as the painted one.

Not really sure, but the fire ring should crush down and seal. Did you see 2m's post about sleeve creep?

If the sleeve isn't fully seated, it'll seat after the engine has had a full temp run. Then you might have a headgasket fire ring problem.

If you deck/mill it like this (unseated), it'll fully seat later, below the deck. Again, fire ring problem. Plus, requiring redecking.

If it IS fully seated, but protrudes a couple thou, the fire ring should compress to handle it. Later, might find some warpage/unlevelness in the head and cylinders, but most of those things are probably warped by now anyway...

Thanks. Im going to bake it again and see if I can clamp it to insure I get a good read on if it is fully seated and is actually protruding or is inproperly seated and too high.

I missed his post when I started this one.
