I haven't seen any Victor heads on the dyno yet but I really doubt that they are going to go 700 hp OOTB with an OOTB Victor manifold on a 505 shortblock.

By the time you port them to max wedge size and buy the special offset rocker arms you'll most likely have as much in them as a set of ported EZ heads.

As soon as someone has dyno info and prices then we'll know if the Victor's are a good deal or not.
