Got my Dougs Headers in!!

Miked out the collector flanges and in my line of work, .0002' is a big deal, but that's building 10 ton machines that are expected to punch out 450 cans a minute all day, every day and the crank runs 1100 to 1200 psi, no ****.

So I need to calm down regarding this stuff. Anyway, I got .400 as an average for the exit collector flange and .305 for the given collector flange, very nice.
