Hi,
If I suspect that the cams may have been changed on an engine, where would I need to look for any identifying marks? They're in the engine, in the car. atm. Previous owner had no clue etc. Car has lots of mods.
I've got a couple of photos but I can't really tell even if they look the same.

I don't have a dial gauge but am planning to get one so this could be a good excuse and just measure the lift to be sure?
