@Rat Bastid I can loan you a set of headers, but they aren't 2".
They are headers for a big block a-body but they are 2 1/4 ", roughly 40" primary tube length, 4" collector 9 1/2 long
They are a mixboxel set, one side has 1 tube thru the k member, the other three thru the wheelwell, other side has one under chassis, two thru the wheelwell, and one thru the k member.
My guess is that you would need a LOT of motor to see an improvent over a 2" set.
