a6 dizzy on z6 head, timing help!

Okay i put back on the a6 dizzy to the z6 head.. how would i know what 0 degrees is? would i read from the top mounting bolt place? would center be 0 degrees or what? help me out!!!

i had the z6 dizzy on the z6 head with my A6 harness but i guess the z6 dizzy won't work... so how do i find 0 degrees now with the a6 dizzy on the z6 head?

do not pay attention to the position of the distributor in relation to the head. use a timing light and just check the marks on the crank pulley. set your timing at ~16 (middle mark)

yeah but where should i have the distributor to start it off? i don't wanna have it at like 10 degrees advance when i start it up...?
