    Never heard of anyone ever needing new heads/thicker gaskets for e85.

    i think what this guy means is lowering the compression ratio by using thicker head gaskets to allow him to run more boost with e85, you dont need to do that if you want to run high amounts of boost 24> psi you need new internals and you wont be able to push that much boost with a 16g (effeceincy wise) if you want to run e85 on lets say 18 psi you will need at minimimum:

    850cc injectors (note you will not have headroom) 1000cc would be better
    walbro 255 feul pump or something similar
