Magnum 360 ?

Hey guys. I might have an option to get a Magnum 360 to play with for my 1970 Sport Satellite. Its drive train is set up for a LA Small Block.

Other than an intake manifold and carb, cam what else would I need to make it work?

I currently have a 340 in there with headers. I assume the headers are not compatible LA to Magnum?

Thanks for your replies!
