Yes, I have the FMS 392 with the stock GT40X heads. I am not sure what all the specs of the motor are. I know that the X heads have 1.94x1.60 valves in them. I am not sure what pistons or cam Ford puts into the FMS Stroker. Mine is a 2006 build of the motor I think, so it would have the newer forged pistons.
I would never had thought that the AFR205's would have fit. Guess I will look into those instead of the AFR185's.
