i think i fucked up my gsr block so im going to take it apart tomoro so iwant to go ls/vtec and i had a couple questions if anyone could help me answer them would be great

1. i heard they last if you do the swap correct without cutting corners is that true?
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?
3. can i put all my gsr internals in a bare ls block?
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?
5. would this be a stout set up?

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

lmk any info you guys have for me would it be worth the work and would it be a fast motor in my ef hatch?? i can get a perfect ls block for like 30 bucks from a friend with 2 heads and extra internals lmk asap guys thanks in advance, john
