Brian i'm not sure without checking. Jeff bough a set of pre bent BBC headers sections to weld up for the dyno test and Mark turned out several header flanges on the CNC. Jeff said it would be a pretty simple process to weld the headers up. I would gess they are 21/2 inch or so but I will check.Jeff will
eventually make a set of tri y headers for the high end stuff. It was funny at the track last year one of the local guys that had a BBC dragster came by and commented on Kevins headers and said in passing them Pontiac just don't flow any air then Kev went out and beat him by a 1/2 second with a smaller motor.That pretty much shut him up.
