318 exhaust manifolds on a 360

Getting tired of fighting the header on the drivers side on my freshly installed 360 in my 69 barracuda convertible. All kinds of clearance issues with steering box, suspension etc. nasty vibrations in the car. I have a really nice set of stock 318 casting# 2843953 and 2465719. Will they work on my 360 ? I also have a left side 340 casting # 3614395 can I use it with the 318 manifold on the right?

Thanks,
Adam
