Somewhere in between these two gentlemen lies the answer for you.  I think
David's right unless the engine has a lot of miles on it, or was overheated.
I should have reused a bunch of cylinder sets that were just fine.  I've
also looked at cylinders that seemed fine, but when cleaned and checked
closely, showed scorching on the inside surfaces of the cylinder.  What is
also true is that keeping the old units clean while dis-assembling the parts
around them is not so easy.  Measure the bore and see if there is detectable
cylinder wear, look for scorching or scratches.  If so, get new ones.  

How many miles are on your reused P/C sets Steven?
