There'd be a desiccant pouch in the suction side; and perhaps a muffler in the compressor outlet. I wouldn't expect two filters.
400-plus psi at 60 degrees is crazy high. Sure you got the correct orifice tube installed? They're color-coded for orifice size; but it's easy to think the one you took out is "black" when it wasn't black when new.
This is the "white" orifice tube I pulled out of my quarter-million-mile AC system on the Trailblazer, along with the new orifice tubes that came in the "kit".

HOW did you measure the "36 ounces" of refrigerant you installed? When using the "pounder" cans, the usual problem is folks don't put enough in. (The "one pound" cans generally have 12, sometimes 14 ounces rather than 16 ounces of refrigerant in them.)
Are you CERTAIN you're getting proper airflow through the condenser?
Does the pressure drop when you spray the condenser with mist from a garden hose?
