i was wondering if swapping out the ls head for a b20 head would make much of a diff??? i heard that the b20 head flows a lot better and helps out a little..not sure if source is really sure either..please give me any info asap..if it does help any one got a b20 head??i know every one is using the blocks so there should be some heads lying around....

 

i guess no one is sure about the head swap??????i would like to know any thing asap..

 

Same as an LS head.

 

A b20 head is identical to a 94+ LS head
