i was wondering if i can use the arp head studs for the d16 and what the thickness is on the head gaskets of the z6 and b7 motor. i was looking at the mr gasket mls head gasket and it was .030 inches with a 76 mm bore.

 

the studs will work just fine, a d16 and d15 are nearly the same, the 15 has a shorter stroke and a different crank, the head gasket is the same dor most of the d seried engines, except vtec and 8 valves. any d16a6 bolton will work on your engine.
