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.




Yes, I'm afraid you're right. My own fault for missing this, but the information sheet that came with the heads clearly says "exhaust ports are raised".
