340 cam bearing alignment?

Keep in mind, what's the next component in the order? A solid piece of metal, as in the cam journal itself! With, lets say maybe 3 thou clearance for the oil to get around. That misalignment is trivial in regards to what the oil has to do. And just like what RRR said above, often it's a compromise when it comes to the clocking of the alignment for the one that acts as the oil transfer galary to the heads.
