The cylinder 7 misfire is likely a symptom of the problem, not the problem itself.
Typically, the catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream 02 sensor reading should be fairly steady. Typically the P0420 code triggers the check engine light if the readings of the two sensors are similar. This is indicative of (among other things - such as faulty sensors in the "emissions loop") a converter that is not working as efficiently as it should be.
I do not believe that it is a problem with a valve/head gasket or cam.

Check ignition timing, timing chain, fuel filter and fuel pressure after you change it. ( if the filter doesn't solve it)

I've got 260K on a 2003 4.8 Silverado. Fuel pump has caused this same problem, 1 after market fuel pump lasted 20,000, the same replacement was 30,000 miles. I made my mechanic put the correct fuel pump from GM using the VIN . The other time I was losing power at about 180K miles it was the cat converter. Hope this helps
