I'm not sure if any of the street cars ever came with HR heads, although I would think Shelby would install any engine you wanted. Although it was a CSX30## car, the car I was told about was I think a comp car, not an S/C. I can't remember if the guy I talked to knew or told me if it came with aluminum or iron HR heads.

I have the HR single four intake, and the correct Lemans carb #3255-1.

I know the owner of CSX3106, and he has it set up with a stock stroke 427 CO, with the DOVE Paquet port HR heads ( basically a HR intake port with the floor raised to reduce the size to a med riser size). He epoxied (filled in) the intake runners of the single four intake to match the heads. 13:1, dry sump, 670 honest hp. He took me for a ride. That car is fast.
