Does anyone know of a heaser or turbo for a-body

NO one I'm aware of, but RA style logs are more than adequate if you can fit them. Very durable and if you look around on other turbo forums there are many guys putting over 1000 hp to the tire with factory logs.

Even modified 3 tube headers will work ok if you dont mind the cut and weld required. Typically though they are thin with thin flanges and wont last very long. Probably better to make your own from stainless and weld ells. Tubes need not be equal length or tuned collector length. Personally I like ID at approx valve size or a bit bigger. Never less than minimum csa of port(IMO). Others think differently. IMO using "too small" for better turbo response is wrong approach. IMO if you have to do that, then you didnt choose your turbine well. Large turbine(to drive the compressor), tight AR, big gate seems the best route to fast response and minimum back-pressure. Not a fan of underlap "turbo" cams either, especially on a Pontiac.

We have turbo headers for a 72 Lemans. Check out pics here in the boost section or the performance classifieds. Just search for turbo headers. The turbo headers for your car also fit 70-81 firebirds. Here is a link to one of the threads.
