theres alot of wrongness from the septics on there!!
RE head differences the head is the same 400 casting used on the M50/52 engines
The inlet cam is alpina spec, the exhaust is standard S52. The chambers on the head are stock, as are the valves. The ports on the inlet and exhaust are a fettled a little. Nothing major thats it.
As for the inlet debacle the M50 inlet does flow a little more but its runner lengths and bore size are different. To my eyes the M50 is better for top end power and the alpina effort is for more mid range punch
The pistons are different but the crank and rods are stock
They also state the airbox is stock 328, no its an alpina effort
