I was even thinking about trying a new set of lifters but hate to do that to the cam/lifter match. Getting desperate here...
Have yiou tried adding/subtracting lifter preload to see if there a 'sweet spot' where they oil better? If you could adjust on them w/the engine running, that would show you pretty quickly if that was gonna help.

If the geometry is off (like Richiehd said), that might cause it.

Obviously a missing gallery plug could do it but I wouldn't have expected to see good pressure.

I'd be a little worried if you heard a noise then the pressure dropped. Any idea where in the engine the noise came from?
