Anyone know the part number for BBC Promaxx 317 heads? I was told the heads were a knock off from AFR but what series etc I’m not certain.

Just to clarify part number for the rockers!

tks

I would just call and ask them.

And IF they are a knockoff of AFR, is it V-1 or V-2? Version 2 uses different stud girdles so Im sure shaft rockers would be different too fwiw. IF you don't find a clear answer, you might want to buy the stud girdles for whatever you think they are, see IF they fit then sell them before spending 1600 on shaft rockers that might not fit. A call to T/D would be your first move regardless
