Yes, the regular Stage VI heads do have raised ports. These are a variation called street stage VI or 383/440 aluminum cylinder head, part number P4876311 (discontinued). They have stock port locations.



No, they don't. 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.
