I was told I need to have a set of 2 1/4 to 2 3/8 step headers to a 4" collector with 30" primaries made for my Belvedere. Who makes a set of 3/8 flanges for 572-13s? I have a guy close to me that can make the headers but it would be easier if I can buy the flanges and collectors. I am coming up empty handed on finding a set pre made. Thanks, Galen

i got mine from indy. they are very nice,cnc'd i think.
on my 580" i dynoed 874hp.i used 2" to 2 1/8" step with a 3 1/2" collector. then i put my headers on,they are 2 1/8 to 2 1/4 step,with a 4" collector. i picked up 0 horsepower and lost 6 ftlb of torque. if i had known that,i would have saved alot of money on custom headers.
