Posts: 19146    Location: bishop, ca | Mike, you should look at this thread, for Tom's customization of Sanderson Block Hugger manifolds. http://www.forwardlook.net/forums/forums/thread-view.asp?tid=33298&... The 55-57 Dodge Hemi heads will have the same exhaust ports, but, the 55-56 guys have different motor mounts (IIRC) and different (coil-) springing, so the Sandersons may well be bolt-on assemblies on both sides of the engine. However, as an alternative to the customization of the Sandersons, these custom headers look like they will easily fit onto the 55-56 applications, and, probably, to the 57's too. I like that the front runners are siamesed, as the exhaust pulses on them will probably help to scavenge the fumes, and, the elevated, transverse front runner (at least, on/for the 57's) will clear the motor mounts. If you or your shop has mechanical-welding capabilities, then creating a version of these headers may well flow better and be more efficient (by creating long-runners, to where they eventually reach their flange-connections) than the Sandersons.
