Will these headers fit gt40p's (pic)

[srtthis]

i bought the mac headers and H pipe tonight for 100 bucks. i did notice a couple places where its been welded together but they are very good welds so this will definately get me buy till i can afford some new ones.

Is there anything to be concerned with a couple welds on the headers?

nah when the motor went back in the race car we had to have a few tubes rewelded
