I hate to say it but 645 from a 505? 12:1 and solid roller......there is something very wrong with that picture. Needs a different head if you ask me.
Here is another one for ya .... this one makes less power but it is also hydrolic cam and a different set of heads with an airgap.

720 or so is very doable with off the shelf, pump gas components.
