Ok! I checked for exhaust leaks and I found one underneath the drivers seat where the header bolts to the rest of the pipe and another leak at #4 (not where I thought tge noise was coming from).

I spun the rod and found it about 1.5mm out of round. A few others were a little bent too. So since it looks like a few rods need replacing I'm going to have a look at the cam and lifters.
