is the b18a1 and the b18b the same block. im doing a turbo build and need to know cuz im getting the 18a block for dirt cheap. im putting the b18b had on it but need to know definitely if the blocks are gonna match no problem

thanx joe

 

if im correct the b18a is the first gen ls/rs blocks and the b18b's are the second gen

 

yes they are the exact same block

 

so i can use the older one with the 2nd gen head and everything still hooks up the same

yeah you cant still use the older one and the "3rd" gen head. i believe the 3rd gen head is a tiny bit better than the 2nd gen. not quiet sure why the reason is. but yeah everything will still hook up the same.
