While prepping a spare engine to replace another troublesome mill, I came across this unusual grind profile on one of the bearing journals...
At what "degree" does the cam bearing journal start to melt?
Turns out one of the oil orifices (that little oil-jet orifice in the top of the head, under the cam tower) was plugged with an amber-like material about the size of a small grain of sand. DAMN!
Now for the other grind...
While sifting through my assortment of cams I discovered that one of these is not like the others!
Look at the plateau on top of the lobe! Now I have to scrounge up a dial gauge and figure out how big those bumps are!
