Default Look at cam, Which lifters are bad?

Recently I paid a sponsor to do a cam swap. The car ran fine for a few dyno pulls, now it makes about 80 hp less. I took a look at the old cam and this blue marks mark where the lifters ground into the cam. HP tuners show a problem in bank one. So, when looking at the cam, does it appear to have a problem on just one side of the motor or both. I'm not sure about the geometry of the cam but hopefully one of you guys can help.

Did they swap the lifters or mention anything about needing any other parts?

nope.
I know that bank one is reading low and my hp is suddenly gone. It just make sense that the old lifters would have groundhough the lobes of the new cam. Just wondering though. If every other lobe controls a different side of the engine, then both sides are damaged. because the two damaged cam lobes arent lining up
as even or odd numbers

You should pull both heads anyways, so you questions is a mute point. It looks like there was an oiling problem to the cam.

Doc, if this is the old cam and lifters weren't changed for the new cam.... The new cam is trashed also. Change cam and lifters.
