thanks for the info smile i'm hoping that it will do the job. I'm not sure what type of headers they are, though i'm pretty sure they aren't Fenton. i've seen plenty of literature on fenton cast iron headers for the I6's and mine just aren't even near the same. i inherited these when i bought the truck and kept them when i had a newer 235 put in. dual pipes looked good
