Default Shorty headers

Maybe try McJacks. Check their website, lots of options. They'll also custom build what you want. Very well made, coated in and out, thick flange. I have them on the motor I built for my '71.

I have a GMPP zz383 in my '66 Coupe. We used Patriot ceramic coated center dump shorty headers. #8019-1. They need no modification and will clear your steering box.

I have the same question. I have a 327 with 2.5” ram horns with 2.5 inch off road exhaust (not side pipes) In my 65 roadster. Will McJacks and Patriot simply bolt in to replace the ram horns or do I need to modify the exhaust?

The McJacks bolted right in to my 2.5” exhaust. No heat riser.
