you set up your roller springs were they the installed height need to be at. if not they need shim or + keepers or retaners or cut the spring cups to get more set up height or longer valves to get them were they need to be installed at . with the spring all together there no break in on a roller no need to take the inner out .your asking if you alum rockers will hold up to your cam ? really it has nothing to do with the lift of the cam but the springs your running you not over 250 lbs on the seat in 680 open the rocker should hold up if good rockers. i run more cam and more spring then your using with good rockers it not to much of a big deal as for oil pressure should be not much if any dif .do not let someone talk you in to running top end oil restrictors they cut down the needed oil to the top end that helps keep the valve springs happy
