C4/C5 Pump & Stator Interchange

Will the C5 pump work ok in a C4...I have built alot of C4's but always layed the C5 pump aside...I noticed it already has the spring/balls removed like we do on the C4 pump for better oiling..The convertor releif valve is the onlything i notice it dont have..One of my old C4 trans had a C5 stator on a C4 housing , that came from Jims trans..Its still running today ,,thanks

Run it !
