When I did the Cat filter mod I had constant air leaks too. Even to the point of taking it all apart to replace the o-ring between the puck and head.
Then I finally realized it wasn't the puck or filter at all, but the bleed screw. I had done so much loosening and tightening in the process of bleeding that it would not seal. I took it out and lapped the seat, put it back and tightened the crap out of it, and no more leaks, no more bleeding. I now have a lift pump, so I will never have to touch the thing again.
