Hooker BlackHeart headers are part of a comprehensive Gen III Hemi swap system that works in combination with engine mounts, transmission crossmember, and exhaust systems. BH2358 headers are packed with value added features that will make your 1966 -1972 Mopar B-Body Hemi swap easier than ever. With BH2358 headers you can use popular transmissions with either left or right hand starters (starter can be installed without removing the headers), and they clear the bulky factory power steering box with no modifications. Installing low mount A/C compressor will require the use of a VVT (variable valve timing) front drive system (2009 & Up VVT accessory drive front cover). BHS2358 headers are designed for a simple installation that provides the most ground clearance possible, and clears the popular torsion bar front suspension. The 304 stainless steel hand welded construction looks great and will last a lifetime.
