This 1967 Nova has been one of the more favored cars to roll into our shop. It is running a 434ci LS engine with powerglide transmission and a single 98mm precision turbo. The polishing on these stainless headers was not necessary, but what was needed was the American made stainless tubing and the double-slip merge collectors. These merge collectors allow slight movement throughout the various heat cycles while still sealing off the header even with the increased pressure from the turbo. Whether you are looking for a standard up and forward turbo header or something custom, contact GPheaders on your next turbo build.
