Really don't know if there is an upgraded head gasket may be a thicker one ? as far as that and the timing cover gasket goes any GM dealer should carry them or be able to get them .Nalley Buick GMC and GM Parts Direct are two vendors that carry them be sure to have your vin # handy when you call so they can look up the correct part #s ,as for the ARP head studs Summit Racing is probably the best place as far as price goes .For the turbo I would contact DDM Works or Werks Performance two of our vendors that specialize in Kappas a bunch of good info from either one . Good Luck !
