TTi header touching passenger side torsion bar #677991 04/23/10 08:42 AM 04/23/10 08:42 AM

The driver's side clears the torsion bar fine, the passenger side rubs up against the torsion bar. Anyone had this issue? The TTi system is a quality piece (I'm not knocking them because there's always the possibility I did something wrong) but I guess I expected it to fit perfectly. 1968 Charger R/T 2015 Charger R/T Scat Pack 2017 Durango Citadel

These are a variation called street stage VI or 383/440 aluminum cylinder head, part number P4876311 (discontinued). They have stock port locations. 1968 Charger R/T 2015 Charger R/T Scat Pack 2017 Durango Citadel

They have stock port locations. i think the '311 head has the intake ports in the stock location but not the exhaust. find an iron head and do some measuring.

I put the headers in myself way back when. Took everything apart, put everything back together, suddenly the header hits the passenger torsion bar. The only difference was new Poly-loc motor mounts. I guess anything is possible when you tear something apart and put it back together.

The 4876311's exhaust port location is identical to a standard Stage VI, which means it's about .4" wider and .4" higher than an OEM head's exhaust port. That's why you have clearance issues w/ the torsion bar.

I have the locking Mighty mounts and they raise the engine slightly. My passenger side 2" TTi is close, so I wrapped the torsion bar with heat insulation. 5946629-Engineinstallation003(Large).jpg (143 downloads) 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

My own fault for missing this, but the information sheet that came with the heads clearly says "exhaust ports are raised". 1968 Charger R/T 2015 Charger R/T Scat Pack 2017 Durango Citadel

Yeah I would make sure the engine is sitting in there according to TTI specs. Chrysler was real sloppy on the k-frames back in the day so you don't know where that engine is until you measure.
