Shim for increased Oil Pressure

This has been my thought process, yes.
Since its general knowledge that the head, valvetrain & Cam's are the known weaknes of the ISX, I can't reinforce the head, but I can get more oil to the valvetrain & cams. I don't know what ideal pressure would be, but I personally want 40psi as a minimum when working hard/hot at 220*+. Personal opinion: ideally I want to be between 40-45 operating range
I pull a multi-axle equipment lowboy and my gross is from 150-200,000lbs (68-90,000kgs), so I tend to lean on my motor a little harder than typical so I just wanted some extra protection if that makes sense?
Also this motor has always been on the lower side of the range when I ask others what their pressure runs. On Mobil Delvac it ran the same or plus 1 pressures as the Castrol listed above, and I have never been comfortable with that. Before this motor I had 4 consecutive Series 60's so I'm just not used to seeing under 40.

I wholeheartedly agree...
