I picked this guy up for next to nothing. No time to work on it and needed to get rid of it. It’s great condition the only thing that does not work is the radio. Not sure why yet. I do need a new exhaust manifold on the right side. My question is will these headers fit? https://www.sandersonheaders.com/sanderson_bsv8_header_set_for_buick_skylark.html Also any recommendations as far as upgrades?
