i have a b18a1 , i hear a b20 head is a lil better , would it be worth swapping my ls head for the b20? and also will a b18B intake mani help at all?

the B20 and B18B head are identical.......your not gonna see any gain.
UNLESS you find a P8R B20 cylinder head. they are very rare and only come from JDM B20 engines. they have larger intake valves and intake ports. they flow better than the stock B20/B18B heads.
