Camshaft Crisis?

I bought a camera stick with a "gyro" but obviously its not working! I neglected to mention 2 things. That the Cam Dynamic Camshaft I used in this rebuild is over 40+ years old ( a late 1980's purchase) and that the spring seat pressure on the Melling's lifters used with the Comp Cam (six pack engine) was 130 lbs. A higher spring rate but a better rotational wear pattern on the lifter face than the Comp Cam lifters @ 110 lbs. used on the (NOS) Cam Dynamic Camshaft. Care to rationally explain this with logic and reason? I don't want bullshit theories about oils and lifter face crowns. I CHECKED ALL THAT!
As I explained in the video, these lifters ALL HAD CROWNS (Face to face) and the cam lobes were ground with the 1 - 2 degree tapered angles. If they didn't, the lifters would NOT rotate on the assembly mock up. I want to hear a "Mechanical Engineering" diagnosis based on "Science", not a "Business" theory based on "Commercial/Corporate" advertising.
Note: What will be the sales "price" on this 1968 440 engine after all this additional tear down time, new parts and gaskets are factored in?
This all fucking free? Hi Performance engine building used to be my passion, now it is becoming an ordeal!
