skip the boltons and LS head, get a GSR tranny swap.
I/H/E = $600
LS head stock = $100
head port and polish = minimum $100
cam gears = $60
plus labor for install if you dont install yourself
or
GSR tranny = $600
LS manual ECU = $100
plus labor for install
tranny swap is WAYYYYYYYYYY more worth the money and performance than boltons and a semi built head on an automatic teg. plus you can swap in the tranny while doing the engine swap to save more time in the future.

a b20 doesnt suck at all, though i do believe it to be a waste of time (for the price of a complete rebuild on a b20 just bore out a b18c1 and put in some better pistons)
see c-speeds integra, it's amazing.
i'm pretty sure that the b20 and the b18b have the same exact head it's why the b20 head was always considred so restritive (it was actually made for the 1.8l b18b)

Yeah your right the Ls and the b20's both share the same exact head. Same part number and all.

pay the extra money and do a cr/vtec with the b20 if you have the b20b that is. i have the b20 in my integra stock motor and it is pretty quick. of course my integra has no interior in it at all. i am going to put a gsr head on it and drop it into my crx. why would you add an ls head how much power that add? cant be much just go with the gsr head and build it right and you will have a quick ass car man
