A leak down test will quickly pinpoint whether you have a valve or ring
problem. My bet is valve. Then you need to determine why the valve
failed. Were the guides replaced? Where the seats cut? Something was
wrong.

Last week I posted a question about stalling at stop lights.  After
further
tests, I did a compression test and found #1 at 30, the others at
130-140.
Had the valves replaced about 5,000 miles ago.  Assuming bad valves, do
all
4 have to be replaced or can just the bad one?  Further, based on the
compression test, could it be bad rings on the cylinders and not the
valves?
