Crane 0012 cams or crower stage 2 cams would work nice.

If you go ls/vtec you shouldnt just slap a head onto a stock ls block and expect good numbers...

You need:

High compression pistons such as JDM ITR pistons
Vtec oil/water pump & timing belt along
arp rod bolts for high reving insurance
new main & rod bearings
gsr/itr head studs
ls/vtec oil line kit
ls/vtec dowels & 1/8 npt plug for vtec head

the list goes on...
