    We have a low mileage 1977 Camaro that was 305 auto with factory air .

    We bought a beautiful 454 for low money and have it in the car now .

    What way do I go and what do I buy to get the exhaust on this car with the Factory AC box there??

    Thank you again for the guide!!!

    I ran a 454 in my 78 with summit branded BBC headers. Didn’t have any issues...you might have clearance issues with tall valve covers. The exhaust should be fine.

    I have had a '70 1/2, '77 and '78 all with transplanted BB and have been happy with Hedman headers, as well as Blackjack back in the day. No issues with tall chrome valve covers on any of them. Also had Hooker Super Comp hdrs on '77 and fitment was trouble free until I added alum. Dart Pro1 heads, due to raised exh ports.

    I have hedman, but ac delete. As Badazz said the tall valve covers will hit the brake booster.
