You will need to check carefully, but most likely not. If the gasket ring
around the cylinder hangs out into the cylinder, then the gasket is not likely
to last for long at all. You really need a gasket made for the 89mm liners
(which AFAIK are all solid metal gaskets, not composites like the original
gaskets).
Since it seems that you are mostly interested in a reliable engine; my
suggestion would be to stick with the 87mm liners. The 89mm units are really
custom made racing parts (which is why the price is nearly double that of the
87mm liners), and I've been told that they tend to aggravate any tendency to
overheat.
Of course, I've never been one to take my own advice, so I have a set of 89mm
liners on the shelf to go along with a lot of other parts that will probably
reduce reliability (but hopefully increase the fun factor). So YMMV and all
that.
PS, I forget who offhand, but someone has suggested turning Delrin buttons to
locate the gudgeon pins, rather than relying on circlips. You aren't the first
to have the circlips come out, with the damage you have observed.
