Default 1.8 ratio rockers question

Hi, I am in the process of ordering the YT rockers. I have a 232/234, .595/.598 cam and PRC 2.5 stg LS6 heads with double valve springs and hardened standard 7.4 pushrods. Will the 1.8 ratio rockers be ok? How much more horsepower can I expect? Do I need a retune? Thanks.

That would really be pushing the valve train, I wouldn't do it with this cam myself.

most cam manufacturers specifically advise AGAINST running higher lift rockers due to increased ramp rate.

stick with stock ratio
