My oil pump is the non adjustable version. It is missing a couple of small parts. Any suggestions?

First of all I'm not trying to prove anything or cause an argument .However in a discussion of piston head shapes there are many conflicting theories .This is one regarding a Honda aprox 6 cubic inch engine testing three piston shapes .https://search.proquest.com/openvie...78da03bec3/1?pq-origsite=gscholar&cbl=2032193 .Again it's just for reference ,draw you own conclusion
