I bought a pair of 1 7/8" headers from a friend he called them TTi's, but they look nothing like TTi's on their site.. any one know what Proparts headers look like? These were in a 440 Dart sport with P/S so they "should fit" a manual steering 383 71 Demon right?

Hey guys I bought a Weiand team G intake for a 383/400 for $100 from a friend - I am debating on running it on my mild 383 that will see 99% street use when driven - or should I bite the bullet and go with the Performer RPM? stone stock 71 383 rotating assembly unknown cam (haven't picked...
