Depends on if you want to make more power or not.
The lumps will make more power & increase intake port velocity more than leaving the boss's in.
The short turn radius is where the lumps really help out & increase port velocity.
If you are looking for a good bump in power & low end torque, install a 1.85" intake & 1.60" exhaust valves & add the lumps.
Adding lumps only makes more power if you install larger valves.

Yeah, the 1.85"/1.6" valves was already my plan as Santucci says to do with a street build. But he just recommends a good performance valve job and throat work for the street application. Not recommending the lumps until the street/strip build. But, the lumps should work fine for the street application too, making more off idle torque up through 4500rpm or more.
