67-69 O Port headers
I am looking to buy the Dougs D568 or the Mad dogs, 67-69;Firebird, which fit better, hang lowest and best performance? Engine 455, 500+ hp. Tips and advice will be appreciated.

I run mad dog 2" round port headers in my '67 and had to slightly dent one tube on the driver's side that the pitman arm hit.

I don't think they hang low but I'll have to go look, the car is at my brother's house.

I bought the Dougs D568, not cheap but they fit really nice with my Canton oil pan, IMI mini starter and the coating looks great. The stock size oil filter fits fine too, they don't hang too low.
