That cam is a copy replacement for the L-82 350 motor cam. (245HP)
Its the same lame GM cam that comes in the lame 350-290hp GM crate motor.
no power and no torque.

It was lame in 350's and is lame in your 327.

And changing to a 1.6 rocker will not fix that.

Your money is much better spent on a better more modern hyd cam and lifters.
Keep the 1.5 rockers. They are fine.

You will notice a big performance difference with a different well selected hi perf cam in your 327.

lobe lift x rocker arm ratio ='s lift at the valve.

1.50 VS 1.60 ratio multiply the valve lift by 1.0666

EG: .450 x 1.0666 ='s .4799

New cam:
Crane Z-268-2 Crane #113521

Another nice choice
summit racing cam # SUM-1788

Here is a nice Howards hyd cam for your 327

All these will out perform the cam you got, reguardless of what rocker ratio you use.

cams have come a long way since 1968.
