neither head studs nor through bolts of the type 912 12 cyl engine used in the 917 was Ti, they were Dilivar
Ti was used for rods and rod bolts
eventually they used Ti for the output shaft for 1 race(Sebring'70) but went back to steel subsequently
Na filled Ti intake valves were eventually and Ti was used for various brackets and even tried on timing gears
160lb of Mg were used in these 542# engines, mostly in the crankcase
