Think this intake swap will hurt performance?

Are those cam specs for 1.5 rockers, 1.6 rockers, or part of both (lift at 1.6 but duration @ .050 with 1.5s)?
I agree with IQ basing it on that last possibility. I think you might lose a little off the 60' but overall the the mph will go up. I'd like to see another 5-8° @ .050 duration in it tho.
