I have a pair of headers off of a chassis car. They are 2" primary and 3-1/2" collector with EVAC ????? and EGT bungs and fit Round port heads. They have been painted, but not coated. The one pic shows dimensions. Any other questions, let me know. I also have a Canton oil pan that ONLY fits a chassis car. The pan was modified and has a 1/4" extra piece in it for use with a front motor plate. I am asking $500 for the headers and $500 for the oil pan + shipping. If you want both, I'll work with you.
