Cam swap without pulling motor

As much as I would like to pull the motor and put in better pistons, that’s just not an option right now. Too many other life priorities. I am going to use the Lunati Voodoo 258/265, 213/220, 0.454/0.475 112 LSA cam that I have sitting around.

Here’s my question. Does it make sense to use 1.6 rockers? I have a set of the Speedmasters from Black Friday. I know I want to keep the duration down because of the sub-8 compression ratio, but would the additional lift be beneficial? I think the Voodoo cams are fairly fast opening anyway.

Truck is 1979 D150 with 360, 727 trans and 3.55 gears, factory exhaust manifolds and iron heads. Heads are currently getting 1.88 valve job and some mild porting. Might do a Performer or an RPM intake.
