Here you can see an a12 engine mount in a 1200 coupe which has a piece of flat steel used to line up the two holes. The coupe had this setup when I bought it. I'm not crazy on the idea, but it works!
this is the first two port s of a A12 head being ported the intake port is finished even thoug it looks rough i have heard that it is a better way to have them as it atomise and breaks up the fuel befor it enters the combustion chamber but the exhaust is still to be smoothed
