The easied way to check for flow issues is to temporary cap off the line to oil filter. This will first force 100% of the oil to the lifters. Also verify the 4-way fitting is in the right orientation so the outlet to the lifters isn't the port with the restrictor on it.

If you've verified that the restricted port (if present) is on the filter side and you'll capped off the oil filter feed and you still have lifter clatter then you know it's a filter issue vs a pressure issue.
