Alloy Heads

The flowing abilty of the head, is general in its info. Are these "Alloy" heads Edelbrocks?
It's hard to put enough head on a stroker. Also, you gave NO info about your build, so it is hard to say anything about what would work and be a benifit over whT could be done with the iron J heads. They can be also ported out to OOTB Edelbrock levels.
