The head porting is your choice I just wanted to warn you. I would not risk it and sent mine to MM and they told me exactly what flow they got out of my head. I think the haed gasket is a special one but let me check on that, it works real good. Also get the M3 head bolts cut to fit your head from MM. They will cut the bolts so you can torque them to their tighter specs and the strech will not bottom out the bolts since they are cut. It really clamps the head good for high boost with the head gasket.
On lifters I use the stock M44 rockers that are on hydraulic lifters. I do have a noisy motor with a tiny tap due to high lift intake cam and my clutch is very noisy but these are small sacrifices to spank 99% of the cars on the road
