Questions about changing rockers

Hi Everyone,

I'm running a ZZ4 cam with Comp Cams 1.52 roller-tip rockers. As a result, the lift is now .480/.517 . I was thinking about increasing the intake rockers to 1.6 and that would yield .506/.517.

The goal for my motor is maximum low-end & midrange torque and hoping for around 300RWHP. Would this help or hurt me? Or would I be better off just going with 1.6 on the intake and exhaust?

Any info would be greatly appreciated!

Thanks.

With free-flowing exhaust heads, closer to single pattern lift will probably increase power.

More cam would be a more sure way to get there.
