Well, I got the correct headers, they fit well, however my oil pan has small kickouts on each side which caused two issues, the left side wont allow oil filter to slide in or out without loosening the header, which only takes 10 minutes to do, I may put oil filter relocation kit on it. the right side the pipe is kinda close to that kickout of the pan, so I applied heat tape to the pan and header wrap on that pipe, a stock pan wouldn't have any issues, the odd thing is if I could have used the wrong rh header ( old a- body one) I would have been perfect. The hooker 3" exhaust fit very well, had to cut a little on the pipes that go to header collector but was no big deal, Car sounds pretty decent, not to loud but has a good tone, I haven't driven it yet. Still assembling the body.
