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.

you'd need to dummy it up and check to be sure but i'd guess no it wouldn't work.

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
