.605/.596 lift with PAC beehives?

My springs have less than 300 miles, they were installed when I had the heads ported. I know they are rated to .600 lift, but would they be ok with a .605 lift?

Pac's catalog says .600 lift for the 1218's
Forgot about the 1518's they are good to .650 lift.

All depends on which ones they are. The 1218's are good to .600, the 1518's are good to.650

The 1218 and the 1518 look very close but the 1518 has a nitrided surface that gives it a different color

I carry them both in stock

Ive had Older comp cam 918's running on my LT1's 0.605" lift, intake and exhaust. Just make sure they have the installed height properly set. It shouldnt be an issue BUT having some wiggle room never hurts.
