Herb Mccandless Headers

There is a moparts member with those headers on a 511 with 440-1 heads, i think his motor is an RB, his name is ARI440.
Another friend of mine runs an RB with 1 heads with 2" TTI headers, he has no inner fenders and he had to scallop the shock support on the pass side, i have done the same to mine in case i ever upgrade to 1 heads.
