b16a head on 90 ls block?

Hey i got an extra b16a head laying here and a slow ass 90 ls. would the b16a block bolt up to the 90 ls block is the code for the block b18? not sure if i heard right but i thought that any b series would bolt together? Any ideas on making this faster on a limeted budget? all my money is going into my car doesnt leave much for this one…
