Looking to purchase the 1 7/8" 383 headers. Motor is built with forged crank, forged diamond Pistons, ported 916 heads, comp hydraulic roller cam and lifters, custom rocker arms shafts etc. still running the stock cast iron intake and heads.... Paper rated at 495 hp and 490 lb/ft. Does anyone have these headers in the different finishes? Can anyone recommend a finish they like? Leaning towards the polished ceramic with the thermal barrier...
