I know this has been around for 8 years, and I have the same question today: is it better to go with aftermarket aluminum *(al la
www.440Source.com) or find what’s become a bit of a grail in a set of unmolested 915 heads offered for a single year 56 years ago. If I were racing, and to fit into the stock categories, I’d have to stay with the iron. Then there’s the cool factor of find a set and porting them as per David Vizard, and creating a head that might compete with the aftermarket and run with the modified at the track, too.
But, if it were a time thing and I wanted to be up and on the road, the aftermarket would be the way to go, because the back yard gems and junk yard bones have been well picked over in 2024…not to mention there’s lots of junk and failed projects being sold as functional or core quality….so you’d have to know what to look for with the item right in front of you.
