we just dropped a new vortec ho350 in a 1985 k-5. question is-----what headers fit best in a 85? we tried using the stock manifolds for now, but the bolts do not line up. what headers have any of you used, and how was the fit? there is a bracket with a bump stop on it for the front diff. on the passenger side. did this get in the way at all? please help us with your feedback. thanks in advance for all your replies.
