Header upgrade
have used many headers over the years, 1.625" - Hedman and Eagle, 5204 Hooker 1.750", 5303 Hooker 1.875". witnessed many dyno tests, trying different headers-no big deal. Have a friend with a wheelstanding big block- he say the headers got smashed and she did not slow down from 9.5 secs. how about the dyno testing Dave and Steves did smashing headers-no big loss.
