CLASS RACER FORUM - Big Block Camaro Headres

Looking to replace my old Doug Thorley headers on my 67 Big Block Camaro. They've been on the car for over 30 years, hate to get rid of them, but they keep cracking. Had them repaired twice just last year, so guess it's time to replace them. Big wheel stand landings are not good for headers. They also have a set of flow master header extensions installed for low to mid RPM, and work REALLY well on the car. Car runs low 10's at 130 MPH. Installing a new bigger Shafiroff Big Block engine and I'm looking for a set of good flowing production headers. I know custom built are better, but they are expensive. I know you get what you pay for but looking for something I can purchase and install quickly. Hooker Super Comp were popular back in the day, but I'm wondering what some of the new technology is available out there.
