Exhaust header temperature
Does anyone know the expected range of temperature in the exhaust headers? My (new) engine is a 3.0, bored out to 3.2 with PMO carb's and hot street/race cams (120/104 Web Cam); 9.5 compression, MSD ignition. I've installed an Innovate AFR gauge and want to ensure the sensors are properly installed with the correct bungs. Thanks.

Steve - I have pre-1975 headers (SSI) and have one bung already installed for previous testing. It's roughly 7-8" from the outlet, above the horizontal plane. Innovate recommends using their extended bungs and/or heat sinks if exhaust temperatures are expected to exceed 500 C / 900 F regularly. This is what I'm trying to gauge. Should we install the deep bungs or not, is the question.
