Cam AND ROCKER HELP NEEDED PLEASE!

Hello Everyone,
I’ve been reading too much! I bought a Comp Cam (Flat Hyd) and some new roller rockers for a 71 LA 318. The specs for the cam are as follows. Intake 462 Exhaust 482 with a lift of Intake 275 and Exhaust 284. The roller rockers I got are 1.6:1. Will these cause problems with too much lift? Should I get a set of 1.5:1’s?
