Jason,
With a fresh piece of paper to start with I would for parts look at Forged pistons, Carillo rods, maybe Crower, new valves and valve springs. New rod and main bearings and new rings.
Look for a multi-piece steel head gasket. New head bolts or studs.
With an iron block I would also look at overboring and using larger pistons.
Plus if the crank rod journal diameters are larger than what is used on Honda's then I would have the crank rod journals offset ground to that smaller diameter both to increase the stroke but also to reduce friction.
Cams can be measured and a new grind can be deterimined based on other engine criteria. But for a Turbo motor you want ot keep duration similar but increase lift.
