Any thoughts on what to do here to make sure there's a good seal and not too much buildup?

If you believe your valves are not seating properly, it is a no brainer: take them out!!! you have done 95% of the job here, just finish it by removing the valves. It is not that complicated: once out, you will be able to clean the buildup on those valves in no time. Then a quick lap on the seat, and you will be able to eliminate the valves as a source of the lack of compression. just be thorough, block the 2 holes in the "valve compartment" to prevent pieces from falling in the oil sump, and catch all lapping compound etc..
There are a few tricks to be able to do a valve removal in 10 minutes rather than 3 hours, do not ask me how I know this (
