headers or not to headers

HP 340 Manifolds to a 2 1/2 exhaust sys. is the hot ticket.Have them Jet hot coated and never have the issues I have had.I have TTIs and and will never buy them again.They still dont fit on the rt steering tie rod and the drivers side frame rail.Also the manual steering is barely cleared.The 340 engine is on stock mounts and installed correctly. headers are not worth it........They now make aftermarket HP manifolds,but they are kinda spendy

Yes and DON'T bother spending big $$$$ on the HP 340 manifolds either. In that same Mopar Muscle Exhaust blow out article on a 300 HP crate 360 the "vaunted(loosely used term)" 340 HP manifolds outperformed 318 log manifolds by 4 HO and 6 torque and only outperformed 360 manifolds(which are WAYYYYYYYY cheaper than 340 hi-po's) by 1 hp and 2 torque...so unless you already have a set of the Hi PO's id just go with the cheaper ones...i mean HUNDERDS of extra dollars for 1-2 HP? Oh and on top of that they tested(in a different article) a extrude honed set which is about as good as it gets for porting them(manifolds) and gained another whopping 1-2 HP.....:(
