Something to think about also, my bennett car has stainless steel headers with full polish stainless side exhaust, there is a lot of radiant heat in engine bay and off side pipes , cools off quicker than steel exhaust when shut down, but I can feel heat in foot boxes and side of car when running. Motor is 427 f.e. 1965 block and heads, cast iron, runs 185 to 190 degrees. The csx car has HPC coated headers and side pipes. The finish is ruff almost like velcro. The reason is to cut under hood and side exhaust temp. The dry sump tank is in right fender above exhaust and even with shield and heat barrier ,coating was needed to keep from overheating
oil. Motor is 468 f.e. Kroyer/Shelby block and heads, 670 h.p. , runs 80 degrees c. You can feel the diff in under hood and side exhaust temp. You would have to work real hard to burn leg, there is that much diff. The Bennett car you don't want to get close to for 10 to 15 min after shut down.
