440 with Indy SR heads - what headers

You’re correct.

I was looking at a TTi application listing on a different site, not TTi.

Just shows you really need to do your homework.

However, as I stated earlier, I do know two people who used the Pro Parts headers in Dusters with raised port Indy heads on RB blocks.

I don’t know if they dropped right in, or if there were some mods required.
