About 15 years ago my dad was on a search for some non smog 360 heads and had a heck of a time finding any. At the time Edelbrocks were $14-1500 or so. He just wanted to put together a mild 360 for my sisters race car. He eventually did find a set and about a year later I found a set of J heads for $100. We have alum heads on all of our race cars now, but for a street car iron heads are fine. Not sure how the speedmaster price for sb heads are but I know for $1000 440 source heads are head to beat for a BB. Buy the time you'd buy a set of steel heads and get the needed work to bring them to usable condition your better off to just buy the 440 source heads.
