How useful do you reckon the oil pump 'massaging' is?

I'm trying to persuade my shop to upgrade... the finish I'm getting is only after the head gets tumbled in zinc shot.

As far as massaging the oil pump... the outlet from the pump gears (2) is the most crucial.... Additionally, I've had an idea I've yet to implement, in adding a 45 degree wedge at the galley outlet (1) where it mounts to the block






4 down....



Next step valve job, then getting chamber volumes to determine depth of final surface machining.


more to come.......
