Oh yeah, I forgot - YF's in my mind are best of the choices you offer. I have a pair of the holleys on my 56 but dont really like them. I look at the Rochesters a little differently: I would take them and throw them as far as I could then run and pick them up and throw them again. Others like them but i cant get them to work.
the other options I like are W-1's or BXOV-2.
