Harley Engine Keyed

I USED THE STEP FILE AND CREATED KEYS FOR THE HEADS SO EVERYTHING LINES UP PROPERLY, I TEST PRINTED A CPL PIECES TO TEST FIT THE KEYS, I ADDED 0.4MM CLEARENCE AND THEY SEEM TO FIT OK, LET ME KNOW IF ANYONE HAS ANY PROBLEMS WITH FITMENT AND ILL CHANGE IT

UPDATE***
I INCREASED THE HOLES IN THE ROCKER COVER ANOTHER 0.4MM AS THEY DIDNT FIT

ADDED KEYS TO THE CRANK, THEY GLUE IN
