PRESSED FOR FAST BLEED DOWN
When reassembling late model Chrysler heads with roller follower/hydraulic lash adjuster type lifters, I found that they bleed down much faster when turned upside down. When I used the vise it would take 2 or 3 squeezes and sometimes they would still be hard. I now use an arbor press with the lifter inverted,. They bleed down in one shot.
