Coil Over vs Torsion Bar

As someone who has competitively RACED these cars, I can tell you the torsion bar suspension is SUPERIOR to ANY of the coil over kits from a handling standpoint. I find it hilarious guys spend thousands of dollars on a coil over kit to gain header clearance, when they could have just bought a good set of headers
Who makes a good set for pre-67 A bodies?I've got a 66 Valiant with a '70 340 & stick.I had to remove ps to install 340 stock headers.Don't want to hack body for headers,not much room on this old narrow chassis!Was considering coil-overs for clearance and serious autocross action. Have done some mods to suspension I won't get into here. What do you think?
