My other thought was maybe the..
Lunati 227/233 at .050, .489/.504 on the lift, and it is cut on a 110 LSA
I hope you didn't order these heads already, nor the cam. Stock vortec heads will not give you enough compression, the chambers need to be cut down and they're a thin head to begin with.
If money is tight id go with a set of the 210cc 56cc chambered procomp heads. And then get a solid cam with face oiling lifters, or at least grooved lifter bores.
Thin casting vortec heads are good if you can pick up a complete used set for $100, but they are NOT a performance head. The small port bowtie vortecs would work well but they're not cheap.
