the cam cover has been polished and its a two bolt main
I have pictures if you want me to email them to you.

Does the cam cover have the emblem still attached to it? If so what color is the right side of the emblem. Does it have the asr?

if the right hand side of the emblem is red it's a 90
if it has asr it's a 92
if the emblem is black without asr it's a 91
