I'd start over.

Bench bleed the MC, install. Use a clear tube connected to bleeder valve.

- Starting with the furthest line away from MC
-- Pump pedal 5 or so times. Pressing the pedal as far down it'll go each time.
--- Hold the pedal all the way down
---- Release the bleeder valve just a little.
----- Do not allow pedal to bottom out while valve is opened.
------ Stop short of that, then repeat until air bubbles are gone.
------- Ensure lines/valves are tightened good.
-------- Repeat process, next furthest away.

Do all 4
Blowing out the lines, you introduced a lot of air to begin with.
If you still can't get rid of the air, you have a leak somewhere letting air in.
