I bought a 93 325is that was missing on two cylinders. Pulled the head off and some of the valves were bent. I’d say whoever installed it didn’t get the timing right. I have the head at a machine shop right now and he’s having trouble finding the correct exhaust valve. From what I’ve learned, those cars come with 30.5mm exhaust valves. The valves in my head have a head diameter of 31.6mm, stem diameter is 5.94mm, and the length is 106.17mm. Can anyone help me find a part number and where to buy these valves?

Try asking VAC. It seems to me that your parts are non-stock (not available through BMW).
