ROTFLMAO...
Seriously, I have cars with both brands of headers and four speeds.
You better have a welder handy because both of my cars needed the lower z-bar arm cut off and moved. The Dougs were slightly better than the tti's for the amount needed to move, but, both sucked you know what for as much as they cost.
If you have a local pick n pull boneyard, get a junkyard mini-starter for $20. I have about 6 of them and none have ever failed me. A mini starter is the way to go.
BTW - I have a very twisted sense of humor.
