Re: 390 stroker block prep question

If I am reading this right and the top edge of the sleeve is .010 inches below the deck, you will have a very strange quench area that might encourage pre-ignition. Generally, you want to keep the quench area as small as possible in high compression engines for this reason.

When a sleeve is installed they generally leave it sticking out of the bore slightly and then cut the deck flat.
