its possible that the needle bearings in the lifter roller failed, then wore down the lobe on the cam.
That has been the typical chain of events if a cylinder goes out of commission. The thing to do is probably flush the oiling system of the engine as well as look at cylinder walls to see if there's signs of scoring / scuffing.
Odds are the oil filter caught the metal particles from the lobe wearing down.
As a precaution, I'd probably replace the oil pump - the unfiltered oil passes through the pump, then the filter next. Metal particles would likely have created wear and increased the tolerances on the oil pump.
Keep in mind if you get any aftermarket cam that has longer duration or different specs over the OEM design, you'll require tuning. Also check if you're going with higher lift if you need new springs or any other components.
From your avatar, I'm presuming this is an '09 SRT8 and the 6.1 does not have VVT
