1.6 Roller Rockers with Vortecs
Can I use 1.6 ratio self aligning roller rocker arms on vortec heads with my cam? the heads are machined to take .520 lift. With 1.5 ratio my cam is at .488.

1.6 rockers put you at exactly .520" valve lift, so your gonna want to double check that the clearance is there. As well as that your springs are up to the task
