I just replaced the head on my 94 525i

I just replaced the head on my 94 525i followed the instructions, according to any videos i find the vanos unit shouls slid in once timming is lined up. problem is i have on 3 occasions installed unit and put back together and the car will start but when i give it gas it stalls.
Question#1, I was not sure the vanos seeted correctly into the cam shaft, it would not slide further in as video show on you tube. e34 m50 vanos install. what am i doing wrong?

question #2 someone told me to reset the computer, take the battery terminal off while the car is running. would you do this while running or before starting the care to reset.

Help.

I would grab a repair manual and a set of camshaft alignment tools. Give our parts specialists a call: 1-888-280-7799 They will help you find the right stuff.
