New piston rings require a fresh hone in the bore. Being able to see the original honed cross-hatch pattern in the bore doesn't count as having a fresh hone.
You have to lightly hone the bore each time you replace the rings. Also important is the assembly... the rings have to be installed on the piston with the mark near the ends facing up. Ring gaps must fall within specs and those gaps need to be placed around the piston properly. If you are putting in a three-piece oil ring, special care must be taken assembling those correctly as well. I've seen those put together wrong many times...
Also, just for informational purposes... if the valve guides are worn out, installing new valve seals on those loose guides won't fix them.
There are too many factors that can contribute to your issue, so I won't attempt to hazard a guess.
