If it ran fine otherwise and the cam lobe isnt worn you could just replace the rocker arm and pivot ball and the pushrod. I use a slide hammer with a collet on it to pull pressed in studs and then use locktight sleeve retainer liquid and install the replacement studs. Unfortunately it looks as if yours has been run that way for a long time though and if the tip of the valve is worn crooked the rocker will always try to slide off putting a side load on the pushrod so probably wont stay fixed.
