Those Aussie Dutras look great. They will be a nice addition to the slant six community. Nice to see people continuing building parts for our old girls. Without this innovation the hobby would continue to dwindle.
Dutra Dual cast iron headers were taken over in march 2018 from this date and will be manufactured in Australia and made available to customers worldwide by Aussiespeed. It was through an article in Hotrod magazine where the Dutra Duals were used for testing and they worked hand in hand with the Aussiespeed long and short intake manifolds.
