Can any dealers confirm the part # for the LT1 used in the auto and LT1 used in the manuals?

I think it's the same part number.

It can't be if the auto has AFM lifters and the manual does not.

My understanding is that all LT1s have AFM lifters, they are just disabled on the M6 in the tune.

Now AFM valves, in the NPP exhaust are different. A8s get them, M6 does not.

I thought that as well, however, the guys taking the engines apart (Livernois Motorsports) are confirming the manual LT1 does not have AFM lifters.
