'89 roller-cam LA 360 w/Magnum heads - new roller lifters not pumping up

Very interesting, we learned some stuff. Mopar has used various methods of metering oil up to the rockers and valves over the years. and I drill a 1/8" hole in a grade 5 bolt for the top passenger side location of the cam plate to lube the timing chain, as this is not a pressurized location.
