I put step TTI headers on the 67 this time around, they are nice quality ..

the only thing I ran into was, starter fitment .. crazy tight, tried 3 different ones

all recommended by TTI .. used the clockable one , it helped a bit

still had to make a small clearance spot in one tube 1/2" round, 1/2" deep or so ..

If I would of had T-bars the struggle would of lasted much longer
