I can't load the video. I can view your photos but not the video.
Several people are saying "not enough oil to the top end".
I can't recall WHERE the oil pressure sender is located on your motor - but if you really DO have 40 psi into the block (beyond the filter loop and bypass spring), then you SHOULD have 40 psi to the lifter oil galleries.
Unlike some motors, the oil flow is not "timed" to the top end via a hole in a crank or cam bearing. BBC gets full time oiling to the lifters.
Oil goes into the block and to the back of the motor, then up to the rear cam journal and then thru a groove in that journal to the lifter galleries - the distributor has to fit properly or the right hand gallery won't get oil pressure. Aside from that, both galleries should be seeing whatever pressure you show on the gauge UNLESS there is a "LEAK" between the lifter bores and the rocker arms.
Best way to check for this is to turn the motor over until the first cylinder is on the compression stroke and both valves are closed - check to see if the lifter preload is "gone" by trying to rattle the rockers and spin the pushrod. Move to next cylinder, rotate crank to put it on compression, check the rockers. If all of the rockers have preload on them all the time, then there should be no place for oil pressure to be "lost" going up to those rockers.

I still feel like there isnt enough oil getting up top to the rockers. it should be splashing and making a mess. its more like slow pooling and dripping down the rocker to the valve spring. It really sounds like the lifters aren't pumping up at all. oil has about 5-10 starts on it. two runs of less than 2 hours a piece, this season. Probably a total of 1 hour on the hose. same with the filter.
