they are out , I am working on a 440 with them right now
the Victor heads are a more serious head with a true closed chamber & requiring offset intake rockers as the pushrods are moved over so the intake port is virtually straight
So far the problems encountered have been that the Eddy valley tray doesn`t fit the eddy heads , the Mopar offset rockers that the heads were designed to work with have been discontinued so you will need to use Indy or Hughes rockers , & the shaft holddown / spacer blocks that Hughes have do not line up the rockers correctly on the head so we are having those custom machined as I type , it looks liek the pushrod holes will need to be opened up to clear the pushrods too , the heads can be ported to Max Wedge size if desired & they will out flow the Indy 440-1 if you do that according to a friend with a flow bench
I cannot figure out why eddy always releases their stuff with only 1/2 the engineering done & no support for needed parts to work with their junk
