Best (easiest) fitting headers 68 Cuda 318

This. :sign3:

I'd take the Doug's 453's over TTI's any day. Not only on price, but fit and finish as well. They also give an extra 3/8" or so of ground clearance compared to the TTI long tube's.

Also, if you have a 4-speed you need to modify the Z-bar. That goes for both Doug's AND TTI's.

He's got an automatic as one of his posts said.
And, yes the Doug's tri-Y design are equally as nice in their own way but try to get them in without pulling the engine out-it's not happening. The big difference in the TTI's is that the tubes start their bend immediately at the flange yielding a slimmer design. Doug's headers are still made the same way they were making headers 60 years ago so they're big and bulky. I still say the ONLY headers for an A-body are TTI's.
