1. i heard they last if you do the swap correct without cutting corners is that true?

Yes (If the motor is built properly)

2. i was thinking about buying the ls/vtec conversion kit along with the arp head studs from skippy would this be all i need to put my jdm b16a head with all gsr internals on it?

Probably...

3. can i put all my gsr internals in a bare ls block?

Yes, but you need to have the cylinders inspected so you know they are in spec etc.

4. what kind of compression should i be looking at i know my gsr/b16 made like 9.3 or something but i heard ls vtec is high compression?

9.9:1 or so

5. would this be a stout set up?

ls block
all gsr internals
b16a head
all gsr internals
ls tranny

It would work...
