1967 351C swap header question

Thank you for adding me to the forum! I have got roped into a project for a friend. He has a 67 cougar non power steering with a z bar clutch set up. The swapped a 351C 4V in the car. When I came on they had a set of hooker headers on. The put an arm hits the headers when it turns left, I think you’d have the pipe smashed before it clearances. Has anyone done this swap and had a set of headers or manifolds they were happy with? I’ll get some pictures soon and upload them!
