===Headers/exhaust=== [http://www.andysautosport.com/headers/amc_rambler_american.html Andy's Auto Sport] has headers for some applications. [http://www.summitracing.com/parts/dou-d109-r?seid=srese1&gclid=CP2xiYG_9LgCFatj7Aod-WkAqg Doug's Headers] sells headers for the 290-401 engines, Headers By Ed has finished and plain header flanges (and gaskets for the later engines) to fit the early 1956-'65 250-287-327 AMC V8 with shared center ports as well as the later 1966-'74 290-304-343-360-390-401 AMC V8 with either rectangular or dog-leg exhaust ports along with other various header parts like collectors and tubing. On some heads the two outer exhaust ports match a 1.5" tube (easy to increase to 1 5/8") and the center two siamese exhaust ports match to a single 2" tube size. Sanderson makes a Cadillac header that could be converted by cutting the flange and slightly bending the tubes to match. Possibly 3-tube Pontiac V8 headers might be re-worked.
