A head to fox body header question

Does anyone have photos of how they cut out for the back tubes that go over the frame rails to exit the engine compartment. Thanks Ward.

2 different cars ive seen that rear tube is right on top of the frame rail pinch weld, it limits placement a little.
On my buddys car he is going to notch it with a half pipe to reinforce it. ill see if I can get a pic.
The other car I seen had the top of the framerail attacked for clearance without any reinforcement.
