As far as wear the reluctor can rise up and make contact with cap if bushings, etc in the cam sensor shaft is worn. There will be clear witness marks on the inside. Side note im actually chasing almost the exact same problem at 5800 and I have TA SI heads.
What lobes are those? I'm getting .332" lobe lift. Doesn't ring a bell.
150lbs on the seat isn't anywhere near enough for those lobes if you plan on having valve control over 5000rpm. Also your theoretical lift is .584". You will be struggling with coil bind trying to get enough pressure. The only spring acceptable for a stock length valve and those lobes with a 1.65 rocker is the PAC 1203. They aren't an easy install either. For that type of lobe I'd want 170-180 seat minimum with a 1.55 rocker. With a 1.65 rocker rpm will be reduced 200-300 more. I wouldn't recommend 5/16 pushrods with them either. I also wouldn't trust spring installed heights and pressures unless you measured them yourself. I've had at least 10 sets of heads come through with no where near the correct spring pressure in the last year alone. Some were likely mistakes where flat cam springs were installed on heads for a hyd roller and others were just bogus spec sheets that weren't even close to the heights/pressures listed. Several were also unknown. It's like reaching into a box of turbos and not looking at what it is exactly and bolting it on your car. Everyone knows what turbo they are running but most have absolutely no clue about the valvetrain stability whatsoever.
Those have more lobe lift than he stated he had but the card is showing much more than he stated also. This is about equivalent to what you had in your fast car!
