Also I recommend shotpeening the rods and use ARP 8mm rod bolts since you will more than likely take the motor over 7400 rpms.

gsr should yield the highest compression ratio... i could be crazy here. higher comp = more power. you want the highest cr possible without the piston wacking the head or the valves colliding. and most b16 heads u dig up are older than dirt, thusly the springs are sacked out and can lead to valve float at high rpm... no good

Re: ls/ vtec question
u can, but i know some people have run into problems with clearance. this was then they advanced timing.
back when i was ls/vtec here is what my plan what. maybe it will help you.
B18 Block
P30 (usdm b16a3) pistons
Shotpeened ls rods
any form of Vtec head
Golden Eagle LS/VTEC Kit (included sandwhich plate and dowels so u dont have to drill the head and all the lines and -an fittings you need)
B16A3/2 Transmission (GSR would also work)
GSR Cams
GSR ARP Head Studs
LS HeadGasket
P30 Intake Manifold
Any 4-1 Header
B16A3 Distributor
P72 ECU (made a HUGE difference over P28 or P30)
The B16A3 Came in the DEL SOL DOHC VTEC model and u can get it in OBD1 (if ur running OBD2 i suggest P2T which is B16A2 00-99 SI) or (if u run OBD0 get the B16A JDM crx/civic sir or teg xsi parts)
if u have any questions i still have alot of information from when i was doing this build up and u can im me on AIM at LUGmyNUTS
