I think so, the L92 has the square intake ports and is basically the LS7 head with only minor differences.. It is a very good flowing head, someone might jump in and say different I think it will but not 100 percent sure.
The only difference I see is the LS9 has a 9.2 compression ratio versus the 10.5 and it is limited to 10 PSI boost. It is selling for 500 to 600 bucks. I'm not looking for the dry sump stuff it's a truck.
