Complete LSAs are are significantly better for boosted or HO applications for a number of reasons.

They have a stronger , more dense alloy and casting process.
They have tougher, more heat resistant valves and they have that swirl inducing wing cast into the roof of the intake ports.
The LSA engine as used in the CTSV and the new LSA powered ZL1 Camaro are both supercharged and benefit from these heads as supplied.

The low cost of the bare castings is more than offset by the final assembled cost of the heads inluding the special valves, spring retainers and rockers (rockers same as sister rectangular port offset valve LS3, L92, heads)

The concept of the LSA and LS9 heads is optimize them for boosted applications where porting is not the answer rather more forced induction pressure and better mixing.
