Check it with clay, but it should work fine. 1.7 rockers will bring your lift up to .529, and 1.73's will put it at .538. It's hard to get a straight answer from Trick Flow, but the general concensus there is that up to .540 lift is safe. You would be a fool to do it without checking it with clay first, no matter what anybody tells you.
Take care
